.com was a bubble, but the web is bigger than ever. Also, 'not perfect' is more important than you make it sound. There are worlds of difference between 99%, 99,9%, 99,99% etc. accuracy; and general perception is easily fooled with 99%, whilst 99,999% might actually be needed for a thing to be viable...a level it might never reach for a bunch of reasons.

Top tier is 80% accuracy right now.
