Sure, but I think it's stupid to be so focused on creating the next network-effect-monopolizer. There just aren't as many opportunites to do that as VC money seems to think. In the Uber-or-Lyft example, most drivers drive for both

I wonder if Shopify is going to help Walmart with warehouse automation as part of this deal. Last year, they purchased 6 River Systems ( https://6river.com/ ), a company very similar to Kiva (Amazon Robotics). https:/&#

The User Guide is a fun read too. Lots of things I hadn't thought about: - pinch points and other safe handling concerns - it cannot perceive glass windows or the edge of a cliff - "entertainment" is mentioned as a possible a

This is a great comment. If you're comfortable sharing any more information, I'd love to know just a bit more detail. What were the technologies or strategies that seemed useless at the time, but eventually succeeded?

Well, they're all good rules, but nobody is going to remember them in the form of a cluttered bulleted list. Jack Ganssle is quoted repeatedly - his blog has a lot of good war stories that illustrate many of these points in much greate
