Any time there is a bug in a smart contract, do we get roll back in Ethereum? There will be more smart contract bugs or operations against intent. I think this is going to become a joke.

Ethereum is not trustable if there is rollback when a contract didn't operate as intended. Can you imagine the stock market operating this way?

BTW has bitcoin ever had a rollback in its existence?

Well if there is a bug in the Ethereum software itself, it would be different. In the sense that miners could decide which branch they want. To be honest they could do this with the current proposed forks as well.

The huuuge problem I see here is that it is the Ethereum Foundation, and Vitalik Buterin himself, who are proposing the fork as a remedy. They should simply say "well duh, fire burns."

No bitcoin never had a rollback. Bitcoin was forked before to fix bugs, but no state was ever reversed and no prior protocol rules were ever violated.
