Fuck AI

Steve Mould is a great example of someone who sees a topic and digs deep because he's curious, but doesn't have a specific theme.

Cody's Lab is another of the original generalized YouTube channels, but it's a lot rougher. He doesn't spend ton of time making clean videos.

Most of the other channels I watch are dedicated to a specific topic, like Practical Engineering, Technology Connections, or Nile Red.

This problem is especially prevalent in the Making community. You can see someone who just enjoys sharing building techniques slowly expand their workshop to one that none of their viewers can afford, and they become a "watch me make something that you can buy from me" channel.

A few that have avoided this are Woodworking for Mere Mortals, and Blondihacks.

There's also people that make crazy projects that would likely kill you if you tried to repeat them, like Hyperspace Pirate.

Just don't be afraid to ditch a channel after they lose their way, sometimes it's best to move on to a different channel that still has a passion.

Unfortunately, it feels like the best ones are the channels that use it as a side hobby, not as a full time gig.
