There was a really interesting interview [1] with Astro Teller, the head of Google's moonshot 'x division', in 2016. In terms of project selection, he focuses on trying to dismiss projects early on, by looking for reasons that a project might fail. And even rewarding employees for scrapping things early on. That doesn't sound particularly unreasonable, but it largely just amounts to a conservative planning process. So then what exactly is the difference between a 'moonshot' and a regular new project?
And so when you look at this sort of selection process it ends up being unsurprising that Google's 'moonshots' ended up being things like Waymo, Google watches, glasses, drone delivery, and so on. One of the largest companies in the world, with some of the deepest pockets in the world, and their 'moonshots' are things dozens of other companies are building as well. It seemed quite telling of the present and future of Google.
