The question isn’t if there will be an AI bubble burst, but when - and how big.

Every wave of significant new tech - no matter how “good” - has followed the same pattern, in part because of inflated expectations and a long lag before adoption delivers real impact (see Solow Paradox).

Muchas de las cosas consideradas como “obsesión” o “frikismo” por la gente que se considera normal, es en realidad motivación intrínseca pura. Ese tipo de motivación, bien dirigida, mueve montañas.

Documenting API Governance How do you document the processes behind API governance?

Since API governance is a service, I thought of using an appropriate documentation method, instead of "reinventing the wheel."

This is ALL hexagonal architecture is about.
The same that was proposed a decade before.
No hexagon, no architecture.

I've often listened to someone blaming old, useless UML but at the same time enhancing how you should use hexagonal architecture.
Please don't follow stuff with horse blinders!

The most useful code isn’t the code that solves every future problem.

It’s the code that’s easy to change.

You don’t need perfect foresight.
You need feedback from real users—and a codebase that can adapt.

Good systems evolve. Give them room to move.

With the potential that generative AI has, allowing it to be used for this… hopefully, in a few years, we’ll look back on it the same way we do on the time when smoking was allowed on buses. Like a completely nonsense.

Too many people accept opinion as fact, or deem anyone capable of stringing together a complete sentence to be intelligent, which is why LLMs seem like a suitable replacement for the people around them.

Building software should be sustainable. Quality and feeling good at the end of the day matter more than constant pressure and accumulating technical debt.
