people have been complaining about software going downhill ever since hand crafted assembler was replaced with C and a compiler. it's the classic "old man yells at clouds".
I don’t think it’s getting “worse” or that it was “good” back in my day.
Software definitely improved for many decades, then at some point started going downhill. Where that happened is up for debate. But UI/Software/Quality is NOT one of those "oh it's just the new generation complaining about the old days" or old people "reminiscing".
