As you should be! It is a rube goldberg solution to a massively difficult problem. Nobody has done it at this scale before and switching billions of value over to a whole new consensus model is going to be an insanely difficult computer science / mathematical / social problem to solve.

That said, I do think the core devs will eventually solve it, which I fully support. We have BTC and ETH 1.0 today and that in itself is amazing. I just don't think it will happen as quickly as everyone hopes it will. It can't. There is just too much ever increasing value on the line pushing on both ends of the demand spectrum.
