He gives an anecdote on how hard it would be to create just one new protein by chance — "the odds are so astronomical that there are fewer atoms in the entire universe in comparison: “The odds bury you. It can’t be done.” - this is essentially Watchtower's 'argument':
1. Ignore the fossil evidence that supports natural selection occurring over geological time.
2. Say how long the odds are over complex molecules developing (this is actually whataboutery - pretend to debate evolution but then switch to talking about biogenesis at the first available opportunity).
NB - a computer scientist is an expert in the field of computers only. His or her opinions on evolution carry about as much weight as my opinions on art.
The theory of evolution is out there to be criticised legitimately. Any biologist who is successful will be awarded a Nobel prize and much more.
