?? Facial recognition is very good already; how would we define a 100x improvement? A 100x reduction in error rate? NIST benchmarked current implementations at a 0.2% error rate with massive databases--1 in 500-- you're saying that you're really confident we'll reach a 1 in 50,000 error rate?
More generally: nothing is inevitable, especially when we're talking about orders of magnitude. Maybe it happens as quickly as we'd hope, maybe it doesn't. Maybe it doesn't even happen in the near to intermediate future at all. That goes for self-driving cars, quantum computers, general artificial intelligence, or whatever.
Moore's law was inevitable, until it wasn't.
