This is also my impression, and why it sounds silly that "petaflops
are not just faster computers, it is a qualitative barrier".

Of course, quantity becomes quality at specific thresholds - e.g., a
PC that becomes powerful enough for the first time to accept real-time
dictation may change to an extent the computing paradigm as far as
human interfaces are concerned. Only, "incrementally higher-resolution
climate models" or "snappier running of scramjet simulations" do not
seem to cut it.
