> The real question is, given all the materials on the internet that can literally tell you why these tools are useful (I mean, surely if you just read the docs you'd find out?!), why have you not done the work?

This is it. All of these tools (with a few exceptions) have legitimate use-cases in the tech industry. The fact that OP hasn't clued into what those use-cases are betrays a lack of adaptability and an inability to leave their comfort zone.

I used to be that kind of person so I get it. It's really uncomfortable having to shift your mental model to accomodate a rapidly changing industry like tech but it's absolutely necessary in order to prevent stagnation.
