The counterpoint is that you will learn jank.
If you started early webdev, you learned lots of tricks, that dont benefit a modern webdev. E.g soap, long polling, the JsonP workaround... and so on
Many of the Llm frameworks will be seen simular. Mcp is already kinda heading in the obsolete direction imo, as skills took over
I’ve learned a lot of stuff that don’t really benefits me right now, but now and then I encounter a situation that made me happy that I did. It may never happens for some, but at the time, I was probably happy learning it.
But there’s some stuff that I don’t bother explore in depth because my time is finite and I don’t really need it. And anything LLM tooling is probably easier than a random JS framework. Vim’s documentation is probably longer than cursor’s.
