My opinion is try as many of them as you can. Also do not consider them static. Just because AI X sucks now doesn't mean it won't kick ass in a few months or a year. If AI Y is great now doesn't mean it won't suck by comparison in the near future. It is evolving extremely fast.

Messing with as many as you can find time will help you learn what works for you and will hopefully give you experience in dealing with them.

I think as more and more jobs are consumed by AI the jobs that likely will be created will often be for those that have learned how to talk to them and utilize them the best.

Now you are likely close to my age and the "job market" isn't as huge of a thing because you know you'll likely age out of it soon.

I still have family members and more though and I want them to be able to survive and thrive whether I am here or not.

So I am often the one trying things and then telling them "go try this".

I prefer AI at this point to a search engine. I ask most questions to AI and only resort to a search engine if I am in one of those rare cases where the returns from the search engine actually give me what I want faster.
