Because of economic downturn in the world, most people have become jack of all trades and master of non. learning skills and not getting a mastery of them because they are testing waters on which of them will eventually pay the bills. I have a friend who during her spare time learnt soap making, baking, sewing yet she's not making money off these skills.
If you are making money from your entrepreneurship, then it makes sense! Otherwise everything is just your hobby no matter what skills you are learning. Also with the introduction of artificial intelligence, it has become even more easier to find direction. You just need to know how to effectively use AI.
Also regarding your comment being jack of all trades, I personally think and individual should have multiple exposures. You can have a job that pays your bills. But if you are spending your weekends sleeping on the couch and watching Netflix, probably you are going to die poor.
Make good use of AI. It has the power to open doors for you.
I think using AI as a tool can be useful but one should not become too dependent on it. AI will not give you anything new. No innovation, no creativity no originality. All you do is just copy pasting from a glorified let-me-google-that-for-you machine.
Also, I would not call anything that does not make money a hobby. Some people have a deep passion, amazing skills and deep knowledge about something but they are just really bad at business. Or they do not care about making money.
