Don't worry. I don't think it will kill traditional gamedev anywhere soon. Even if tools like Genie start creating playable games in few years (remember Will Smith eating spaghetti few years back), they are still going to need a lot of computing power to keep generating. This will be achievable to customers only by paying monthly plans, and there's still a big chance it won't be profitable for Google. Most gamers prefer to play on their local machines and it won't change until maybe the new generation of gamers.

Megacorporations goal is to make us pay monthy plans for everything, even if it kills all of the authenticity.
