He's not referring to the fact that one pool is having issues. He's referring to the issue itself as the evidence. The issue is that transaction fees for ETH are so high right now that this pool stopped sending payments, because they are the ones covering the fee.
There're for sure better options available now that can replace Ethereum completely. Ethereum introduced the concept of "smart contracts", which made it so successful. Now many coins are creating a better interface & system for creating & managing smart contracts.
I'm not expecting any flippening anymore, not at least with Ethereum.
you reference better alternatives, what are some projects you think may be a better alternative than ETH?
