People say that, but almost everything brought forward has non-crypto equivalents that are likely superior, and don't involve the opportunity cost of burning large amounts of fossil fuel, and redirecting huge amounts of valuable compute resources towards merely sustaining it. Maybe someday some clever smart contract thing will really take off; and maybe someday some non-PoW coin will really matter, and maybe one day all the stabilizing regulatory infrastructure will be replicated for that hypothetical coin. It could happen. But it hasn't happened yet; so far it looks more like a ponzi scheme. And even if the tech really does evolve into something truly valuable, the route to that promised land could still have some surprising ups and downs, and if coins really continue growing, real-world economic pains along the way. Also - the tech behind it all isn't the same thing as the specific instantiation of todays coins. Even if the tech finds a niche, todays coins could still turn out to be a ponzi scheme.
