I'm not on Twitter... I don't have a Twitter account and think the signal/noise ratio there is... low so that's why.

However I do live in meatspace and I don't think Bitcoin has a 'scaling' problem. It has an educational problem. Everyone has heard of email. Everyone has heard of gold. Everyone has heard of inflation...

Bitcoin is like combining all three (sort of) and there are enough wallets and apps available right?

How much does it cost to open a Lightning channel?
