On: SHA-1 Collision Detection on GitHub.com

And in the latter case, most human programmers will be unemployed, and thus unconcerned with hash collisions.

If you were generating hashes on the gpu for collisions, according to https://hashcat.net/forum/thread-4314.html

A single titanX does 2^9 hashes per second. Suppose you had a 10,000 Gpus (expensive but not impossible) you can do 2e13 hashes per second.

In 100 years there are ~3e9 seconds, so 6e22 hashes. Still magnitudes below 90.

Sha1 isn't still crackable by brute force in a meaningful time.
