Despite the hype, this blog post makes it clear that Autopilot is just a very simple camera based system that requires human monitoring (but is still very useful in my personal experience). Now they are releasing a software update that uses the previously unused radar hardware as well as machine learning to achieve better results. This is exciting because they're going to keep releasing software updates over the air and the software is just going to keep getting better and better.
The fact that the hardware is shitty doesn't concern me. Google's self driving car project depends on a Lidar system that costs $75,000 today. That's almost four times what the average car costs, and it doesn't work in bad weather. Regardless of how good Google's software is it could mean nothing if Tesla acheives a similar or better result using cheap commodity hardware. The hardware will only get better over time at the same price.
Tesla is in a better position to bring full autonomy to market than anyone else, since they control the hardware, the software, have cars in the field etc. For this reason I wouldn't be surprised if Tesla becomes the first company to break a market capitalization of $1 trillion dollars. Computers gaining the ability to move around the world with drones and autononomous driving will have an economic impact bigger than the introduction of the internet. Where we are now is meaningless. What matters is that Musk has stated the goal and we have something in the field today that can be updated iteratively over time until it's perfect (which will be never). We may not be very far along this journey, but we've taken those hardest first steps towards the next big technological revolution that will once again change everything about how humans live, the implications of which we can't even begin to imagine.
