What's wrong with blowing things up. Mythbusters did it. Gomez Adams blew trains up. Electroboom is always zapping things and himself a lot of the time. So what if Photonicinduction has created a channel where electricity is harnessed and released for amusement.
It's all in good fun and if it attracts an audience good on him. I don't watch it myself but I watched someone cutting and baling hay over the last three days with a tractor he rebuilt. I'm not going to sneer at them. Some of the stuff I watch on YT I'm not going to admit to here.
If I'm any guide most channels on YT are subscribed to because viewers connect with the presenter. Whether it is Fran Blanche, Diodegonewild or Bigclive or any of several dozen others if what they do interests me and they entertain me that's all I want. Hell, during lockdown last year I did some jigsaw puzzles and started watching Karen Puzzles on YT. Now there's a niche interest. But she really puts the work in and I respect all content creators who can do that.
