The crux of this argument seems to be that UUIDs are too long? Which I disagree with. I can't memorize them, no, and it would be cumbersome to try to say one aloud, but these aren't situations I've ever found myself in. Does it make the URL in the URL bar longer? Yeah, but does that matter?
It matters aesthetically. A huge site like Amazon might care about that, otherwise it's not a high priority.
UUIDs are at least visually kind of white noise, companies have no problem+with+links?that=look&like=this, so why do they care about UUIDs?
