Eli5 why do computers get slower over times even if properly maintained?

I’m talking defrag, registry cleaning, browser cache etc. so the pc isn’t cluttered with junk from the last years. Is this just physical, electric wear and tear? Is there something that can be done to prevent or reverse this?

Registry cleaning and other stuff doesn’t solve all problems completely. Some errors still remain, some junk still accumulates, more software is installed/updated over time and this new software is often “heavier” and slower-working than older versions. If you format a drive and do a clean reinstall of the system with (optionally) only the old versions of the software it had at the start, it should work faster again.
