Monopoly

I played Monopoly with my kids for the first time today. I bought a simplified version and we played two and a half rounds. Tonight I sat down at my computer and I programmed a little bit for fun, without any AI, for the first time since I really hopped on the AI bandwagon. It took me six months to really enjoy programming again. For a while I felt like any time spent coding and not focusing on some higher level thing like positioning or feature sets or marketing was a waste of time since AI agents had come so far. I also felt like I wasted years of my life focused on this thing that’s suddenly no longer that special. I regretted not making more art in my twenties. I regretted not going to art school. I regretted prioritizing a “good job in a big company” over almost everything since I was around 20. Now, over 20 years later I think about what my goals and values are now, and how I want to spend the lesser 20 years before my body and mind really go down the hill.

I don’t know. This was fun though. It’s not going to make me a millionaire, no one else will ever run this code. It’s not event that great, just a quick quick sketch over an hour or so after the kids have gone to bed, but it was fun to do, and to think about, and to just enjoy without it needing to be good, or correct, or valuable. I don’t know what the future will bring, and I’m tired of trying to figure it out.
