I think you're missing the point - as the video explains there is little practical value (at the current time) in a feature that increases transaction limits regardless of how clever it might be at a technical level. If it doesn't provide a market advantage that can entrench it for the long haul it's nothing but a fanciful distraction until the next contender comes along incorporating the very same ideas but with more whistles.

There's an alt-coin singularity event on the horizon - maybe 2-5 years out - where big problems will have been solved and all of the best-of-breed approaches will have amalgamated into the surviving protocols (just as has happened with every single software platform in history, laying waste to the competition). My bet is with cryptovestor on this one - for better or for worse it will be successive versions of ethereum and bitcoin that are left standing, the rest is just a game of musical chairs.
