The talk is also provided in other formats:

Did you check that link yourself? The only other format for this talk is Real— not all of us consider that an alternative.

There's also MP4 for the four individual sections of the talk (see phone icon).

Ah, I didn't see that. Well, that's much less of a hassle than Real— thanks!
