If you went back to 2021 with the knowledge you've today, what'd you do?

If you went back to 2021 with the knowledge you've today, what'd you do?

That isn't far enough back to make meaningful changes for me. If the weeping angels could send me back to the 70's with the knowledge I have today into my 70's body however then I could prevent many bad decisions, mistakes and could make better uses of opportunities that presented themselves to me. I could also save a few lives. It would be a massive list. I have not done much since 2021 for this to be useful however. Maybe I would get a different brand of food for the deer I suppose.

Let's suppose the subtext of this question is about "AI" advances in LLM.

For me, probably not much change from the trajectory I am already on with respect to cybersecurity and ethics. Although I'd dump a couple of chapters I wrote.

But I love these questions because, if you do have a vision and sense for such thought experiments, then re-frame the question as if asked in 2027:

  " If you could go back to the end of 2023 with the knowledge you
  have now (2027) about what happened these past few years, what would
  you do? "

Maybe a better mental exercise for seeing where things are, and perhaps where they're going?
