@brennen i think program stability is far less important than format/API stability. like i don’t care if the electric water heaters they have in 20 years aren’t the same as the way i heated water as a kid (over the stove). what is important is that the recipes i wrote which use hot water are still usable.
with respect to format stability, i think there are some trends which are very depressing (the move away from XML; React user interfaces), but there is a lot of really good standardization work happening now as well. so it’s a mixed bag and not entirely good or bad i don’t think.
