In reality giants like John Deere have such chokeholds on the market that they can either buy out "disrupters" or bankrupt them. Hardware is so costly and slow moving compared to software that the swiftness of startups compared to incumbents isn't enough. Tesla for example is basically a charity project where the automotive industry is being given the technology in order to encourage them to adopt it. If Tesla was being run for purely economical purposes the incumbents would have moved to buy it or crush it.
