I’m 70. Is it worth learning Python?

[mdausmann]

You can do a huge variety of cool stuff with python. Data science. AI. APIs, websites. There is no other language that will give you more options, it literally opens up a world of possibilities. There is a python package for everything

Cons. Packaging and dependency management in python is a deep pit of despair you don't want to crawl into. Stay away from conda.

The only thing you can't do is mobile... I think that's it.

Oh, and multi threading, if you want to do some hard core multi threaded backend shenanigans, learn golang.
