Good, but still not enough to scale.
That literally is scaling up. Scaling has nothing to do with the magnitude of improvements. You clearly don't know what "scaling" means
So we can doube-triple current tps? We will need like 100x and more. This can help, but it is not a remedy on 10x or 50x more transactions we have now.
I`m not supporting scaling by raise block size to the moon, we just need more space now. Raising block size and adapting segwit in same time give us much more space and open new possibilities that segwit give us. But it all need TIME. And we run out of it, like 6 months ago.
Nope.
That's all bunk, spam attacks have been driving the transactions fees, not real economic activity. We're running below the 3-7 tx/s capacity today, and have been since the BU coup started to unwind.
Maybe you could wave your hands faster?

That'll work
