many such case, things that were just not worth the cost are now within reach

expect that most of the software stack than we have been using will be totally reinvented

we should all be way more ambitious in the system we build

I've been telling people for 25 years that Jane Street is not interested in formal methods.

No more!

And we're actively hiring to form a new formal methods team!
