I didn't say it can be fixed. I said they can continue trying to fix it and it appears to me that they are adding more layers of complexity on top going in circles like a dog chasing its tail and not knowing it. I suppose there is some 0.0001% chance they solve the implausible, but I have a deep understanding of the issue and I can see the odds are stacked against them. I say their odds of fixing it are akin to winning the Lotto. But I am not claiming 100% omniscience so we will see... I have to at least admit that I can't be 100% sure... but I am talking about my level of understanding and thus my appraisal of the probability of them solving the fundamental issues.
Charles knows me very well (and he left Ethereum long ago and one might assume he pocketed some of your ICO money). The others don't. (And thankfully for that otherwise they would be reading my posts and copying my block chain technology since I have some solutions, although I still don't have a solution for Ethereum's specific problem)
In particular they can't get scaling with sharding and still retain Consistency. It violates the CAP theorem. And they can't solve the economic Tragedy of the Commons on verification without centralization.
One can argue they will just centralize it (and perhaps even obfuscate that it is centralized in some techno-babble that no one can understand), and then continue innovating on a centralized platform. Well that defeats the point and won't enable huge adoption markets.
