How AI Is Already Changing The World (both good & worrying)
Very clear positive examples (2025–2026)
- Medical diagnosis support (sometimes better than average doctors on specific tasks)
- Extremely fast protein folding → huge acceleration in drug discovery
- Coding assistants → many developers 2–5× faster
- Personalized tutoring (especially mathematics & languages)
- Accessibility (real-time captions, sign language → speech, visual description for blind)
Real things people worry about (already happening)
- Mass production of misinformation / fake news / fake videos
- Very good phishing & scam emails
- Deepfake porn & blackmail material
- Algorithmic bias (hiring tools, loan approvals, policing…)
- Energy consumption of biggest training runs
- Automation of many writing / customer service / entry level programming jobs
Most balanced sentence you can remember:
AI is a very powerful general-purpose tool → like fire, electricity, internet → can be used for incredible good and incredible harm
