It’s well documented it veterinary literature, you can believe the studies or not 🤷♀️. It’s not like it kills your cat instantly, you just deal with diabetes kidney or urinary issues in the future. Not sure why someone would not try to prevent that.
So far the only actual study we have on this says it’s not a real thing. Sure, some cats have different preferences but it’s not like you are torturing your cat with normal bowls and need to run out and buy special ones.

If you’re feeding your cat an infinite supply of dry food without a feeding schedule you have bigger things to be concerned about than whisker fatigue.
Remember the magic meatball episode of Rocko’s modern life?
Blockchain (simplified) is a giant excel spreadsheet that you can never edit, only add to. I struggle to think of any applications that is a benefit for, and even then append only databases would already do it better.
One of the benefits is supposed to be decentralization, but people tout that as a benefit for things like house deeds, or identification, or whatever. Imagine how massive an append only excel file of every house with every owner change etc etc included in it would be. Then we once again only have the people who can afford to store that much data storing it, and we are back to where we are now.
It doesn’t really solve any problems, it just is a worse version of what already exists.
