No, because Bitcoin was and is miles ahead in terms of infrastructure, adoption, and market cap. The people with so much invested in Bitcoin had every incentive not to allow a competitor to succeed. But now thanks in part to Peter's idea (not sure if he was the first to conceive it, but I learned it from him first) of shifting the exact distribution and ownership of Bitcoin to a new blockchain, it is possible implement a PoS system that will have the support of the entire Bitcoin community because they do not have to give anything up to have a stake in the new system and they automatically have the same investment in it as in the original blockchain.
