The person in this video was adamant that the sun revolves around the earth (yes really) possibly stemming from radical religious beliefs that most reasonable people would take as a sign of mental illness. Don't forget that he is essentially arguing that something that already works won't work.
I can't believe anyone would believe that cryptocurrency blocks can't go over 1 MB every 10 minutes when plenty already have. Most users don't even sync with the main chain even though they can. The whole thing is mind melting.
Why keep doing this? The second layer stuff is a solution in search of a problem and everyone behind it keeps trying to convince everyone there is a problem.
Do you realize that even a poorly made hash table can be updated 10 million times per second on single core of a 14 year old computer? Weren't you the same person saying that a node that just has to download blocks and send them out couldn't be run on a VPS for some reason?
Are you sure you understand these things and haven't just been reading misinformation?

I remember back when I mined, his pool Eligius would embed bible verses into the mined blocks. We had quite a chat about it back then.
