I think you do not understand just how much stuff it out there. Just in the web world, can you do React and Angular and NodeJS and Spring? Have you really looked at the CSS specification? That's a career in itself. Moving slightly to mobile apps, what about Jetpack Compose for Android and the equivalent for iPhones? Electron? Or classic programming: How is your SQL, including stored procedures? Note that Oracle is different from Microsoft is different from MySQL. Want to learn ABAP? How about writing a back-end system in Java, with a front-end in JavaFX? I'm just getting started... No, you cannot learn all of this sufficiently to be even remotely productive. You may, like me, be aware of a lot of it. I'm sure you could pick any single new platform or technology, and become productive in it in a few weeks or months. But to be a real generalist, able to do it all? That is simply no longer possible.
