They've spoken to this directly. Facebook has tried to migrate to something else (generally with a small team leading the charge) a few times.
Let's say that there's 1M lines of PHP code right now handling Facebook's site. In the time it takes the team to re-write those million lines of code, another million have been written. So they can never catch up. Almost like Zeno's paradox, except the turtle moves faster :).
All that aside, you can teach PHP to pretty much anyone, and it's rather effective at solving web problems.
For quite a while they had some really smart people working on APC to help with performance, they've since switched horses to work on HipHop and the like to get the performance they need.
