Frankly I think a lot of full-time-employed technical people are largely experimenting for fun in the context of things that might eventually be useful to their employer. AI is cool and fascinating stuff and when I have a few idle minutes at the end of my workweek I love catching up and experimenting with the latest and greatest, but with an eye towards company problems and on company time, and sometimes using company datasets. That means company vendor approval and financing of my efforts.

In my personal life, when its time for fun, I close the laptop and go do some gardening.
