The reason I brought up roomba wasn't to talk about Lidar or vision necessarily. It's more a story about how the first-mover in a technological space became entrenched in what works and became resistant to investing in newer technologies. The result was rival companies taking away marketshare from a market roomba once defined. Roomba has since incorporated lidar and other innovations after being stagnant for a decade, but its too late - their competitors now dominate the market.

To complete the analogy, Tesla is invested in vision-only technologies, while its competitors are making gains with Lidar and other tech that Tesla refuses to acknowledge. It's very reminscent of Roomba in the mid 2010s.

The Matic is a cool little robot though.
