Correct.
Small project turns into a bigger project, I think I can get through some complicated piece and BAM. I'm fighting silly typing issues and writing tests for stuff I would never have to do if I used typescript. While majority of my stuff is not that complicated, it seems there is always something.
I also wear a bunch of hats. So retaining all the new knowledge gets a bit hard. Sometimes its easier for me to fall back to patterns I used over the past 20 years of full stack development. If I had the time I would use typescript everywhere.
