The thing is, it really did change, but it's not just nostalgia. The old videos worked because people were making comedy without thinking much about algorithms or monetization - it was more experimental, with jokes that had time to land, weird pauses, absurd humor that nobody touches nowadays because "it doesn't convert." YouTube literally penalized videos that didn't keep people's attention in the first few seconds, so comedians had to adapt to a much faster and more predictable format.
What also changed was the whole culture around comments and sharing. Back then jokes spread more organically among friends, there was less pressure to make content that would "go viral" immediately. Now everything's optimized, titles are clickbait, thumbnails scream for attention. It's not the creators' fault - it's the system forcing them into it. Kids who grew up with that rougher, more improvised humor have memories of something that was made with fewer restrictions, and it's hard to replicate that when the platform punishes exactly that kind of creative risk-taking.
