I really recommend listening to Vlad Zamfir, who has interesting things to say about crypto in general: https://www.bloomberg.com/news/articles/2021-07-15/vlad-zamf...

This is not a rant for or against Bitcoin or Etherium. It's more to point out the persuasive and idealistic rhetoric of crypto gets confused with what may happen in the real world as people work on use cases.
