I like "technological phase change".

For one thing, I don't think scientific change can run off to infinity. The speed of light and the maximum quantum information storage kind of limits the ability for information to be stored and transmitted (at rates way higher than we're currently doing, but still).

A phase change is when matter changes it's form- ice melts into water, water evaporates into steam. The rules of how ice behave, for example, follow nice, predictable patterns- right up to the point where the ice melts and turns into water. At that point new rules of how the matter behaves- rules which can not be extrapolated from the rules of how ice behaves. Note that the phase change is not, does not have to be, instanteous. Portions of the ice can be melted into water (following the new rules), while other portions remain stubbornly ice.

What we're approaching is a technological phase change- a switching over to the new rules.
