Generative AI: the good vibes and the bad
What you'll see
The math, plainly
Linear algebra without the algebra. A 3×3 mixer you can drag, a real 2D attention model you can step through, and a zoom from 42 numbers to trillion-parameter models.
What's inside a modern AI
Hover over a real architecture diagram, then zoom in on the system prompt, safety filters, code sandbox, and helper models.
How agents act
The think–act–observe loop, plus MCP and Agent Skills — how models reach out to tools and reuse procedures, with the security trade-offs.
AI & code
How "vibe-coding" works, why models pass software-engineering benchmarks now, the honest caveats — and how cheap software lets almost anyone build their own tools.
Costs & trade-offs
Datacenter energy, hardware shortages, wealth concentration, creative work, and the entry-level jobs being hollowed out.
Honest evidence
A clear separation between measured evidence, company reports, estimates, and one explicitly labeled scenario.
