> I’d see it as the same situation as Camera makers when digital was coming at the horizon. They only needed to be there when the tech is ready, and had no need to bet the farm on making it a reality sooner than necessary I'm not so sure this was really true. For example when the mirrorless transition happened Sony had basically bet the farm on making it a reality and as a result they dominate the mirrorless space in marketshare. If a new product is sufficiently better than existing ones then it can overcome the capital advantages of existing players. Especially with modern day VC funds pumping billions into high growth startups. I also think you have to consider that very few people in legacy companies have cutting edge expertise. Walmart is not going to have the calibre of robotics, AI, or engineering personnel that Amazon does.
