I mean, Steve Jobs designed the iPhone but calling him an engineer is still a stretch. There's definitely a layer of separation between the Luckeys and Carmacks of the world, akin to the Jobs/Woz dichotomy. It's not inherently bad, just notable. The lot of us armchair critics and software engineers aren't regular users either, so we're also poorly suited to guess how the market responds.

In the end, it will be judged as a product. The market will like it or it won't. All I know is that it will be an uphill battle to match the install base of the Oculus Quest, let alone the Valve Index or Vive.
