I think there is more footgun in the hooks, especially rules of hooks. I worked with Junior dev and I can see unexperienced dev misused hooks more often than lifecycle.

There is no reason why. Thise study explain “how”. Only reason that marketing/fashion have an impact on human is nature. “How” is what they studied

What does obsolte mean actually? Today you still can build web app by jQuery.

Obsolete does not mean you cannot use your knowledge anymore. It means that community are shifting interested into new thing, maybe for better or for worse.

In this case, I do not think stick with JQuery or old framework for 5 years is productive for programming. If that happen to any community I would say that is a downside, not an upside.

Except for that fact that community and newly graduated junior developer are ahead of me in something. I can live with that

They produce software. Some of those software are used. That is enough. Skill to surpass unforgiving territory is not as important as result.
