From a strictly logical perspective, they might not. But I would wager a fair amount that there are Bayesian methods used somewhere in the stack supporting those two things. I also suspect that genetic algorithms designed for scheduling purposes probably help your phone call data get transferred somewhere along the way. That is to say, just because the two technologies are not obviously connected doesn't mean the former isn't used somewhere to achieve or improve the latter.

That said, even if there is no presence of Bayesianism in the efforts producing those tasks, his point was surely that, in today's world, an education sufficiently advanced to train people to do those things would certainly include Bayesian statistics somewhere in the curriculum.
