What? I was not aware the scaling problem was so high!
Yes. It is. The clear trend is that transactions per unit time are increasing. At some point in the very near future, bitcoin will hit a ceiling that it has not before hit - the situation where blocks are persistently full.
Why are most people saying that everything is fine and that scaling will come then?
I think BJA would argue against "everything fine". I'm in the camp of "things are gonna soon suck, and will continue to suck, until the pain rises to the point where most admit things need doing".
