I'm pretty confident they'll do it right.
For those who don't know, the founder of IOHK (which created ADA) is one of the co-founders of ETH.
I'm confident in his ethics and his ability. I'm not so confident in the ethics of the ETH project anymore.
-edited above since I get rate limited every time I post more than two posts in a day, read the following as a response to the post calling me a liar below:
Ok, I edited to take out the reference to when he left since apparently I made a mistake on the dates -- I thought he was still in the ETH foundation when that happened.
However, he was one of the few voices calling for the ETH foundation not to hard fork to just roll back the DAO hack. The ETH foundation did what was expedient for them financially, and ignored the core tenet of cryptocurrency.
Fact remains, ETH was an immature cryptocurrency, run by immature people, who made immature mistakes. He was one of the few who called them out over it.
You can see what he has done over the years since with IOHK to bring maturity to the space. I think the results with ADA speak for themselves.
