full stack 'becomes a trap'

The speaker retracts an earlier endorsement of learning "full stack" development and argues the market shifted sharply starting in 2025. Two changes explain the shift: (1) the rise of ei coding tools—named examples are cursor, chargeably, and here a co-bilot—which make it much easier to scaffold cross-domain work, and (2) a market overcorrection where "everyone started doing full stack," producing an oversupply of candidates who know a little of everything but fail basic interview questions. The practical consequence, per the transcript, is that "full stack is being replaced by someone who knows really well front-end, but very basic knowledge of back-end." Front-end developers are struggling in interviews because shallow, simultaneous learning across Java, CSS, DevOps, back-end, and front-end leaves gaps.

The recommended strategy is explicit and actionable: pick one domain and make it 80% of your focus; spend the remaining 20% on basics of the adjacent domain and on ei tools to supplement delivery. Examples and specifics the speaker names: focus deeply on front-end or back-end skills, learn V0 and front-end design principles, and use ei to "execute at 10x speed" so you can credibly claim specialist expertise plus AI-enabled cross-domain delivery. The speaker also flags a timing note: by 2026 onwards, employers will increasingly demand true expertise (especially for scaling systems) combined with competence in AI tools rather than shallow full-stack generalists. Follow the 80/20 allocation, present yourself as a specialist who leverages ei for other parts of the stack, and emphasize ability to ship maintainable, scalable systems when interviewed.
