This is Madness
As a developer, your first duty is to the customer, your second duty is to the product and your third is to your team. Choice of language or library isn't even in the top 3. Use what works, use what you know. It's not going to crumble in your hands just because something new came along.
Afraid of getting left behind?
It'll all be there when you get back.
The Hacker News posts, the Medium essays. Even the posts on <your favourite startup>'s engineering blog.
You might have missed a few libs that blew up, got big and then just as quickly died.
Who cares? You made something. Now you can take a moment to learn about the Next Big Thing... if you want. Or you could just make another cool thing with the stack you know.
