Basically they want to build rack scale computers with open/ auditable firmware all the way down and really design the hardware for "hyper-scale" like computing. That means, no VGA/ USB/ DVD on the server, power and networking will probably be solved for more servers at once, there will be APIs for all of the low level stuff that is probably inconsistent with your typical Dells, HPEs, Lenovos, SuperMicros.

I find, Bryan Cantrill talks are generally worth it to watch even just for entertainment if for nothing else.
