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.

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

With release 1.11b we completely removed the web panel feature. You can find a statement on that in the release notes here zen-browser.app/release-note...
Also, we've added this nice button in the Glance menu!

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.

This is extremely sad and a huge disaster for the entire Japanese cultural industry. And the fact that it started specifically with Studio Ghibli makes it even harder.
Was wondering why OpenAI chose to showcase images in the style of Japanse art studio Studio Ghibli - but not, Disney characters, Marvel comics etc.
I suspect b/c Japan is the only major country that made training on copyrighted works legal.
Expect no other country to follow after this…

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.
