Both methods have trade-offs as in there are positive and negative merits for both approaches. Using both systems requires the sensor data to be fused together to make real-time decisions. This is the whole point, why people are trivializing this problem, and why it is easy to believe that they are just trying to scam people by going cheap on using multiple sensors. If you want to argue that it is better to use Lidar then explain why apart from 'others do it'. The podcast, and previous explanations by this guy and others that agree with him (which occurred way before some shortage issues) is about what is the best way to solve autonomous driving. You don't solve it by simply adding more sensors. There are multiple hours of technical information about why this guy Andrej thinks this way is best. Others make arguments for why multiple sensors and fusion makes more sense. No one knows the correct answer, it will be played out in the future. Maybe what some people care about is cheaper cars. That is not what the podcast was about, that is not how the Lidar + stereo camera vs. stereo-camera only decision was made. And in terms of the advancement of human civilization it is not interesting to me whether Tesla has good or bad quarterly results compared to what is the best way to solve the engineering problems & the advancement of AI, etc. I don't really care very much but it is slightly offensive when many people just dismiss engineers who are putting in tons of effort to legitimately solve complicated problems as if they are just scam artists trying to lie to make quick money. That is also a stupid argument. No company is going to invest billions(?) of dollars and tons of engineering hours into an idea they secretly know is inferior and will eventually lose out because they can have a good quarter. That is not a serious argument.
