May? What kind of crazy optimist are you?

Personally, I'd bet on will.

I've run into problems with my ultrabook in rooms with vga-only projectors. they're definitely still a thing.

mini-displayport to VGA adapters are also still a thing :-P

No office which uses VGA is going to have an adapter handy which isn't already lost in a random drawer somewhere with dead batteries and random keys.

I've worked for shit tons of media and design companies who couldn't even keep track of the regular cables to charge their mobile devices (used for testing).

People would "borrow them, just for a minute", then leave it on their desk, where someone else would take it, then not know where it came from and sweep it into a pile of other bits and bobs somewhere.

You have to be a proper strict to keep this sort of thing in check - it makes you unpopular in the office, badgering after people.

yes, but I'd have to have known in time to have one (:

And audio/video conferencing still won't work most of the time.

I've had good experiences with https://appear.in, it's based on WebRTC (no installation of anything, no accounts necessary). It might not be suitable for corporate use, but for private use it's great.
