Love Bitcoin uncensored, great links.
Very interesting to hear Vlad say that "it's quite realistic that we might see the first version of sharding in a couple of years". I'd say that gives you your answer
I completely agree with the vids, the crypto community really needs to wise up to how far Eth still has to go and how hard their challenges really are. Their choice to start with smart contracts and then try to make the blockchain square fit in the round, scalable hole gave them a kind of first-mover advantage on usable tech in the wild while it was small, but things will continue to get progressively more difficult for them as they grow. The high price and pressure might cause them as many problems as it has afforded them advantages if they start to creak under the weight of expectation and investment.
Tangle, data chains, sharding and graphene are all very interesting I agree. I think David took the right approach though; starting from the bottom up and thinking holistically about design rather than piecemeal additions to a single, seminal innovation. Slow and steady wins the race.
