Perfect recall is not necessarily a desirable thing. Black Mirror explored some aspects of this: https://en.wikipedia.org/wiki/The_Entire_History_of_You

Actually real life people with perfect memory have a problem with relationships, cause they remember all the fights and arguments and insults.

For most people "forgetting" is a valuable phenomenon. There are lots of minor injuries and torts which are better off forgotten than recalled. Doesn't even have to be things other people did to you, but things you did yourself while learning.

Okay, so then who will be remembered above all of the other noise in our heads in a thousand years?

Mental real estate is very expensive, and our ability to forget is what allows us to remember the things that are important to us.

Forgetting can be a wonderful blessing.

Yes. The reason why the decade one grew up in usually gets labeled "the good ol days" by said individual.

Another reason is many things always going downhill, and people remembering them, while younger people grew up already familiar with the decline.

That's not very different a story than the continuous progress myth, just has an opposite sign.

Fact is, some eras progress for the better, and others regress (Weimar Republic, the fall of Rome, and countless other examples). And that's overall. In specific things, it can vary as well in opposite direction to the overall trend.

And long periods are relatively stagnant, such that people for centuries on end, or even millennia, live more or less the same (e.g. most rural areas in Europe between 400 A.D and 1900 A.D.), and few speak about the "good old days" there.
