No, maybe now would be a good time to check...

No, I only know older versions of it. I've only programmed i386
assembly usefully before, I've played around with micro-controllers as
well but not for long.

On desktop PCs yes, but you've got many more computers in your home/car
that aren't PCs.

OK, so it's just the abstract/slides needing someone to explain them.
As an aside, in which other disciplines does research get quickly used
by all the people who would stand to benefit from it? I'd be inclined
to say that CS is particularly bad, but then again I'm most familiar
with it and therefore can't even pretend to be a dispassionate observer.

Indeed I do! flying over to the US to see it in real life would be a
little extravagant.
