Whats the process for Google to make this sort of thing? Does some 7 figure exec say we need to make it easier to draw bikes and then Google gets their army of 10x engineers to make this happen?
It takes a lot of skill, tact, and product acumen to get things out the door -- probably the same set of skills as you would need outside Google. (Except that within, you have access to more and better resources, but the bar is much higher.)
Obviously, this doesn't mean that every idea will stick... a lot of them won't -- some don't make money, some don't provide real value, and some are just terrible ideas. But it's a much better process than just top-down alone.
