22ms here. 22ms there. "Focused on human perception" here, "Focused on human perception" there.
And suddenly we have what is basically a supercomputer unable to perform anything without lag.
We're focus on client apps, where we're really focused on human perception. In that sense, I'd consider 22ms or 2ms as instant (for startup). I wouldn't consider 2s as instant.
I'm not saying Dart doesn't have room to get better, but there are diminishing returns at a certain point.
