Is there a term for when people reminisce something and think those were the days at the same time think everything contemporary has gone to the dogs?

Like my uncle who is an old car enthusiast who thinks ambassador was the greatest car ever made in India yet if you are really objective about it was truly a bad car (wrt milege, comfort, safety, design, etc).

I feel the same reading the comments here. Really don't miss anything about the old internet, especially the era of VSNL which was a downtime provider with some internet in between. Everything is much more amazing now. Want to learn anything from programming to chemistry there are hundreds of freely "animated" tutorials. God how easy my studies would be with the wealth of easy instant knowledge we have now. Add to that the amount of crazy content created everyday for every niche, it is just amazing (you just need to know where to look).

E.g. I just found out about two channels recently called Captain disillusionment and Great scott on youtube and I've learned so much about two really different things, things which I didn't even know I was even interested in.
