It's all a little over my head, at least in terms of applicability to my life, but anyone who's dabbled in Microsoft's cloud-connected developer tools will find things to watch (if they haven't already watched them). Or it might just give you a sense of the workings behind the online services (shopping, banking, etc.) that we all take for granted in 2021.
The mix of promos, interviews, and demos is at least interesting, and there's precious little filler, other than Satya Nadella's 'inspirational' keynote - he always seems genuine but never actually says anything concrete. [Or maybe I haven't forgiven him for cancelling Windows 10 Mobile? Perhaps both!]
