Unfortunately everything he says is true. But also, unfortunately, in Silicon Valley the marketing people have taken over again. This includes, and maybe even started with, ironically, Apple. Especially since he talks about XEROX it really hurts. To anyone interested in the history of computing and so on - Apple never invented anything. NOT A THING. XEROX PARC has been the true invention force in Silicon Valley since the 70s; it was just people like Steve Jobs who were 100% marketing-oriented sharks who took their ideas and turned them into products.
So what does that mean? The video is supposed to fool you into thinking "it's a great product" and you as consumer are in control. When in reality, it's just good marketing, and despite a shit product people are still going to buy it. That's for example exactly the case with the iPad. No one needs it. It serves absolutely no purpose, there is literally zero product design going into it (it's all just technical advancements that made XEROX's visions, like Mark Weiser's UbiComp scenario possible). And then with proper marketing people think they need it, and buy more Apple devices.
Blizzard has been doing the same thing. Just look at this Blizzcon in its entirety. There is ZERO development going on. It's video shorts for many franchises (Hearthstone, Overwatch, WoW) that they sold as new content and big stories on the opening stage. It's some quickly developed random add-ons that just follow a template of the previous ~30ish add-ons for their existing products (new heroes in HotS, new cards in HS, new hero in OW, new co-op commander in SC2). They even sell a simple "remake" as a new product for a fully fledged price (WC:R). There is absolutely no creative, innovative work visible to me; it's all just "use this template to add a new skin and sell another DLC".
That's just the industry these days. What's sad is that Blizzard is following it. They used to be different. But now they're like Steve Jobs... fooling you into buy mediocre, overpriced products that you don't need. Gutted.
