IV. System Solutions: Long-Term Prevention and Control
Fresh Air Systems
Continuously exhausting indoor polluted air and introducing filtered fresh air, maintaining 24-hour air circulation, are currently recognized as the most effective long-term solution. They are particularly suitable for slow-release pollutants such as formaldehyde after renovation (which volatilizes for up to 15 years) and have become mandatory in Europe and the United States.

Advantages: Requires minimal frequent operation, can be integrated into smart home systems, and is suitable for all types of homes.

Air Purifiers
Combining negative ionization, ozone, activated carbon, and HEPA multi-layer filtration technology, they specifically address complex pollution and are suitable for immediate purification needs. However, regular filter replacement is required to maintain efficiency.

How are internal political and economic challenges, such as the rise of populist movements and the energy crisis, affecting the cohesion and future of the European Union?

Internal political and economic challenges, particularly the rise of populist movements and the energy crisis, are creating significant strain on the cohesion and future of the European Union.
While these challenges expose deep-seated vulnerabilities, they also act as catalysts for policy changes and integration.

The Rise of Populist Movements-
Populist movements often gain traction by exploiting public dissatisfaction with the "establishment," which frequently includes the EU. They thrive on economic anxieties, cultural identity concerns, and a feeling that national sovereignty is being eroded by Brussels.

Euroscepticism and Disunity: Populist parties, both on the far-right and far-left, typically advocate for a less integrated Europe, promoting national-first policies and, in some cases, openly calling for leaving the EU.
Their electoral success in member states can lead to a more fractured European Parliament and a Council of the European Union where reaching a consensus on key policies becomes increasingly difficult. This can slow down or even block progress on crucial reforms.

Undermining Rule of Law: Some populist governments have been accused of undermining democratic norms and the rule of law within their own countries.
This creates a direct conflict with the EU's foundational values, leading to institutional clashes and legal battles between national governments and the European Commission. This tension erodes the mutual trust that is essential for the EU to function effectively.

Shifting Policy Debates: Even when not in power, populist movements influence the political agenda. Their focus on issues like immigration and national identity can push mainstream parties to adopt more conservative stances, leading to a more polarized political landscape and a retreat from the EU's shared liberal values.

The Energy Crisis-
The energy crisis, exacerbated by geopolitical events like the war in Ukraine, has exposed Europe's vulnerability and intensified internal tensions.

Economic Strain and Inflation: Skyrocketing energy prices have fueled inflation, squeezing household budgets and putting pressure on energy-intensive industries. This has created a cost-of-living crisis across Europe, which has in turn fueled public anger and support for anti-establishment parties that promise to protect national economic interests. The uneven impact of the crisis across different member states creates a risk of social fragmentation and unequal economic recovery.

National vs. European Responses: While the EU has attempted to coordinate a unified response, many member states initially prioritized their own national interests by implementing their own subsidies and price caps. This "go-it-alone" approach threatened to undermine the EU's single market by creating an unlevel playing field and highlighting a lack of solidarity.

Catalyst for Change: Despite the immediate challenges, the energy crisis has also acted as a powerful catalyst for change.
It has forced the EU to accelerate its transition to renewable energy sources, recognizing that energy independence is a matter of national security.
The crisis has spurred new joint procurement initiatives and infrastructure projects aimed at creating a more resilient and integrated European energy grid.
The long-term goal is to reduce dependency on volatile external suppliers and strengthen Europe's strategic autonomy.

“Fewer Squadrons, Bigger Risks”-Can the Indian Air Force maintain air superiority with far fewer fighter jets than sanctioned?

Indian Air Force (IAF) cannot maintain air superiority with a fighter jet fleet far below its sanctioned strength.
The IAF is authorized to have 42.5 squadrons to effectively counter a two-front threat from China and Pakistan, but it currently operates with a significantly smaller number. This shortfall creates critical vulnerabilities, particularly as its aging fleet of jets is phased out.

The Dangerous Shortfall-
The IAF's squadron strength has plummeted to around 29-31 squadrons, the lowest it has been in decades.
This is primarily due to the retirement of old, Soviet-era aircraft like the MiG-21 and MiG-27 without timely replacements. The IAF is set to retire its last two MiG-21 squadrons, a move that will further reduce its strength to near parity with the Pakistan Air Force, which has around 25 squadrons. This numerical disadvantage is a major concern.

Ageing Fleet: The IAF's fleet is a mix of modern and aging aircraft. The backbone of its fleet, the Russian-origin Sukhoi Su-30MKI, is a capable platform, but many of its other jets, including the Mirage 2000s and Jaguars, are due for retirement in the coming decade.

Slow Replacements: India's indigenous Tejas Light Combat Aircraft (LCA) program has been plagued by delays, and the slow pace of production means it can't replace the retiring aircraft fast enough.
The more advanced Tejas Mk1A, designed to be the backbone of the IAF, has also faced delays in production and delivery.

Modernization and the Way Forward-
Despite the challenges, the IAF has a clear roadmap for modernization and is investing heavily in a future-ready force.

Next-Generation Aircraft: To address the immediate shortfall, India has acquired the Rafale from France, a highly advanced multirole fighter jet that provides a crucial technological edge. The IAF is also pursuing the Multi-Role Fighter Aircraft (MRFA) program to acquire 114 new fighter jets to bridge the gap.

Force Multipliers: The IAF is also focusing on acquiring and developing "force multipliers," such as new mid-air refuelers and Airborne Early Warning and Control (AEW&C) systems, to enhance the combat effectiveness and range of its existing fleet.

Indigenous Programs: For the long term, the IAF is banking on indigenous programs like the Tejas Mk2 and the Advanced Medium Combat Aircraft (AMCA), a fifth-generation stealth fighter, to ensure long-term self-reliance and bridge the squadron gap.

The IAF's ability to maintain air superiority will depend on its capacity to accelerate the induction of new jets.
The current situation, with fewer squadrons and bigger risks, is unsustainable for a nation that faces a two-front threat. While the IAF's professionalism and training are top-notch, bravery alone cannot overcome a significant numerical disadvantage.

In an Age of Drones and AI, Will Human Fighter Pilots Eventually Become Obsolete?

For over a century, the fighter pilot has been the ultimate symbol of national power projection, technological innovation, and military prestige.
From the dogfights of World War I aces to the stealth-dominated skies of the 21st century, human pilots have been seen as irreplaceable—fast-thinking warriors in machines that extend their senses and reflexes.
But as drones, artificial intelligence (AI), and autonomous combat systems mature, the question has shifted from whether unmanned systems will assist pilots to whether they might replace them entirely.

The future of air warfare may be less about human heroics and more about machine dominance. Yet the road to that future is far from straightforward.

The Case for Obsolescence: Machines Don’t Tire, Fear, or Hesitate.

Advocates of unmanned and AI-driven warfare argue that the fighter pilot is already approaching obsolescence. Drones like the U.S. MQ-9 Reaper, Turkey’s Bayraktar TB2, and Iran’s Shahed-136 loitering munitions have demonstrated their effectiveness in surveillance, strikes, and swarming tactics. Unlike human pilots, drones:

Can endure extreme G-forces beyond human physiological limits, enabling sharper maneuvers.

Eliminate risk to human life—loss of a drone is far cheaper politically than a downed pilot.

Process information faster with AI, reacting to threats and opportunities in milliseconds.

Swarm in numbers, overwhelming defenses with quantity and coordination rather than relying on a few high-value manned aircraft.

The U.S. Air Force’s “Loyal Wingman” concept, in which autonomous drones operate alongside crewed fighters, hints at a transitional phase. But the long-term implication is clear: why keep humans in the cockpit at all if machines can outperform them?

The Case Against Obsolescence: Why Humans Still Matter

Yet, writing off the fighter pilot too quickly risks overlooking the enduring value of human cognition in complex, unpredictable combat. AI is powerful, but it is bounded by its programming and training data. Air combat involves not only physics and tactics but also psychology, creativity, and improvisation.

Adaptability and Intuition – Pilots often make split-second decisions in novel scenarios that machines might misinterpret. AI struggles with “unknown unknowns,” while humans can extrapolate from experience.

Ethics and Accountability – Decisions about lethal force still raise questions of responsibility. Can a machine be entrusted with the authority to decide who lives and dies without human oversight?

Electronic Warfare Vulnerability – Drones and AI systems rely heavily on communication links and sensors. Sophisticated adversaries could jam, spoof, or hack these systems, leaving them blind or hostile. A human pilot in a sealed cockpit remains harder to compromise.

Symbolism and Deterrence – Much like aircraft carriers, fighter pilots serve not just a functional but a symbolic role. A nation with elite pilots embodies prestige, morale, and cultural narratives of courage.

In short, humans bring adaptability, judgment, and legitimacy—qualities that machines cannot fully replicate.

Hybrid Warfare: The Likely Middle Ground-
The most plausible near-future trajectory is not total replacement but hybrid man-machine teams. Human pilots will operate as commanders, leveraging drones and AI as force multipliers rather than direct replacements.

Loyal Wingmen – Australia and the U.S. are developing drone “wingmen” that fly in formation with manned aircraft, scouting ahead, jamming radars, or striking targets.

AI Copilots – Programs like DARPA’s Air Combat Evolution (ACE) have already shown AI defeating experienced pilots in simulated dogfights. These systems could soon act as onboard copilots, handling routine tasks and leaving humans free to focus on broader strategy.

Attritable Aircraft – Instead of investing in ever-more expensive crewed jets, militaries may produce swarms of cheaper, expendable drones to accompany human-led strike packages.

This model preserves the pilot’s decision-making role while expanding combat capabilities through AI-enabled autonomy.

Geopolitical Implications-
The shift toward drones and AI is not merely technological but also strategic. Countries with weaker economies but strong drone industries (like Iran or Turkey) can offset their lack of advanced manned fighters with cheaper unmanned swarms. This democratization of airpower is altering balances of power.

For the United States, the challenge is maintaining qualitative superiority. The F-35 and sixth-generation fighters may be cutting-edge, but adversaries investing in drone swarms and hypersonics could sidestep traditional airpower hierarchies. Future conflicts may see fewer Top Gun–style dogfights and more battles between AI-managed networks of sensors, shooters, and decoys.

The Human Pilot’s Future-
So, will the human fighter pilot go extinct? Not immediately. The next two to three decades will likely see a diminished but still central role for pilots, as they command hybrid teams of drones and AI. However, as AI decision-making matures, the cockpit may eventually be seen as a liability—a bottleneck where human limitations constrain machine potential.

Still, history reminds us that predictions of obsolescence often fail. Tanks, artillery, and even manned bombers have all been declared outdated, only to evolve and remain relevant. Fighter pilots may follow the same path: fewer in number, more specialized, and increasingly integrated with autonomous systems.

Conclusion-
The age of drones and AI does not spell the end of the fighter pilot, but it does mark the end of their absolute dominance in the skies. Humans will continue to play vital roles in strategy, judgment, and oversight, but machines will increasingly shoulder the burden of speed, risk, and volume.

In the long run, the future of air combat may not be man versus machine, but man with machine—a partnership where the pilot is no longer the lone warrior ace but the conductor of a symphony of autonomous weapons.

The myth of the fighter pilot may fade, but their strategic importance will endure, reshaped by technology yet still tethered to the human element.

Can artificial intelligence help catch cyber fraud before it happens — or will it be used to commit more fraud?

Artificial Intelligence (AI) presents a fascinating and somewhat terrifying dual-edged sword in the realm of cyber fraud.
It absolutely has the potential to help catch fraud before it happens, but it is also undeniably being leveraged by criminals to commit more sophisticated and widespread fraud.

How AI Can Help Catch Cyber Fraud Before It Happens (Defense):
AI and Machine Learning (ML) are transforming fraud detection and prevention, moving from reactive to proactive measures.

Real-Time Anomaly Detection and Behavioral Analytics:
Proactive Monitoring: AI systems constantly monitor user behavior (login patterns, device usage, geographic location, typing cadence, transaction history) and system activity in real-time. They establish a "normal" baseline for each user and identify any deviations instantaneously.

Predictive Analytics: By analyzing vast datasets of past fraudulent and legitimate activities, AI can identify subtle, emerging patterns that signal potential fraud attempts before they fully materialize. For example, if a user suddenly attempts a large transfer to an unusual beneficiary from a new device in a high-risk country, AI can flag or block it immediately.

Examples: A bank's AI might notice a user trying to log in from Taiwan and then, moments later, attempting a transaction from a different IP address in Europe. This could trigger an immediate MFA challenge or block.

Advanced Phishing and Malware Detection:
Natural Language Processing (NLP): AI-powered NLP can analyze email content, social media messages, and text messages for linguistic cues, sentiment, and patterns associated with phishing attempts, even if they're expertly crafted by other AIs. It can detect subtle inconsistencies or malicious intent that humans might miss.

Polymorphic Malware: AI can help detect polymorphic malware (malware that constantly changes its code to evade detection) by identifying its behavioral patterns rather than just its signature.

Identifying Fake Content: AI can be trained to detect deepfakes (fake audio, video, images) by looking for minute inconsistencies or digital artifacts, helping to flag sophisticated impersonation scams before they deceive victims.

Threat Intelligence and Pattern Recognition:
Rapid Analysis: AI can rapidly process and correlate massive amounts of threat intelligence data from various sources (dark web forums, security bulletins, past incidents) to identify new fraud typologies and attack vectors.

Automated Response: When a threat is identified, AI can automate responses like blocking malicious IPs, updating blacklists, or issuing real-time alerts to affected users or systems.

Enhanced Identity Verification and Biometrics:
AI-driven biometric authentication (facial recognition, voice analysis, fingerprint scanning) makes it significantly harder for fraudsters to impersonate legitimate users, especially during remote onboarding or high-value transactions.

AI can analyze digital identity documents for signs of forgery and compare them with biometric data in real-time.

Reduced False Positives:
Traditional rule-based fraud detection often generates many false positives (legitimate transactions flagged as suspicious), leading to customer friction and operational inefficiencies. AI, with its adaptive learning, can significantly reduce false positives, allowing legitimate transactions to proceed smoothly while still catching actual fraud.

How AI Can Be Used to Commit More Fraud (Offense):
The same advancements that empower fraud detection also empower fraudsters. This is the "AI arms race" in cybersecurity.

Hyper-Personalized Phishing and Social Engineering:
Generative AI (LLMs): Tools like ChatGPT can generate perfectly worded, grammatically correct, and highly personalized phishing emails, texts, and social media messages. They can mimic corporate tone, individual writing styles, and even leverage publicly available information (from social media) to make scams incredibly convincing, eliminating the "Nigerian Prince" typo giveaways.

Automated Campaigns: AI can automate the generation and distribution of thousands or millions of unique phishing attempts, scaling attacks exponentially.

Sophisticated Impersonation (Deepfakes):
Deepfake Audio/Video: AI enables criminals to create highly realistic deepfake audio and video of executives, family members, or public figures. This is used in "CEO fraud" or "grandparent scams" where a cloned voice or video call convinces victims to transfer money urgently. (e.g., the $25 million Hong Kong deepfake scam).

Synthetic Identities: AI can generate entirely fake personas with realistic photos, bios, and even documents, which can then be used to open fraudulent bank accounts, apply for loans, or bypass KYC checks.

Advanced Malware and Evasion:
Polymorphic and Evasive Malware: AI can be used to develop malware that adapts and changes its code in real-time to evade traditional antivirus software and intrusion detection systems.

Automated Vulnerability Scanning: AI can rapidly scan networks and applications to identify vulnerabilities (including zero-days) that can be exploited for attacks.

Automated Credential Stuffing and Account Takeovers:
AI can automate the process of trying stolen usernames and passwords across numerous websites, mimicking human behavior to avoid detection by bot management systems.

It can analyze breached credential databases to identify patterns and target high-value accounts more efficiently.

Enhanced Fraud Infrastructure:
AI-powered chatbots can engage victims in real-time, adapting their responses to manipulate them over extended conversations, making romance scams and investment scams more effective and scalable.

AI can optimize money laundering routes by identifying the least risky pathways for illicit funds.

The AI Arms Race:
The reality is that AI will be used for both. The fight against cyber fraud is becoming an AI arms race, where defenders must continually develop and deploy more advanced AI to counter the increasingly sophisticated AI used by attackers.

For individuals and organizations in Taiwan, this means:
Investing in AI-powered security solutions: Banks and large companies must use AI to fight AI.

Continuous Learning: Everyone needs to stay informed about the latest AI-powered scam tactics, as they evolve rapidly.

Focus on Human Element: While AI can detect patterns, human critical thinking, skepticism, and verification remain essential, especially when faced with emotionally manipulative AI-generated content.

Collaboration: Sharing threat intelligence (including AI-driven fraud methods) between industry, government, and cybersecurity researchers is more critical than ever.

The future of cyber fraud will be heavily influenced by AI, making the landscape both more dangerous for victims and more challenging for those trying to protect them.
