Some computer programs crash - just as some possible superintelligences would kill all humans.
No most computer programs crash, it's just that most people never see them because said programs are repeatedly tested and modified until they no longer crash before being shown to people (this process is called "debugging"). With a self-modifying AI this is a lot harder to do.

No *most" computer programs crash [...]
By "no", you apparently mean "yes".
With a self-modifying AI this is a lot harder to do.
Well, that is a completely different argument - and one that would appear to be in need of supporting evidence - since automated testing, linting and the ability to program in high-level languages are all improving simultaneously.
I am not aware of any evidence that real computer programs are getting more crash-prone with the passage of time.

Not a surprising result, perhaps, but the details of how Geoff taught AGI danger and the reactions of his students are quite interesting.
