Use Cases for Smart Contracts in the next 10 years

What are some use cases you can think of for smart contracts in the next 10 years? What applications can only be built with smart contracts or are make more sense on the blockchain? Or Bitcoin Maxi, No Smart Contracts all the way?

Also the fact that once deployed fixes are not possible is another big nono from my web dev point over view where I am shipping foxes regularly. What about that as well?

PS: I am learning about Rust and Solana right now and get the feeling that smart contracts are terrible in most cases and my motivation is tanking. I need to see some value in this whole thing…
