Spec-driven development is not a return to waterfall.
AI makes coding faster, but speed was never the real problem. The real bottleneck is still requirements and specifications.

A very nice feature of @jooq.org - implicit joins!
No need to explicitly join child tables to retrieve parent's columns. SQL that feels like ORM :)

I wouldn’t call Angular or React and Spring Boot or Quarkus “full-stack”.
This is “dual-stack” because you have to learn two languages and two ecosystems.

Many people think software engineers will lose their jobs because of AI.
I see it very differently.
AI can generate 100% of the code and tests. Like I described in AIUP.
That part is done.
But software engineering is not coding.
