Back when Elon Musk was running Tesla, he was known for saying that LiDAR technology (basically laser beams that measure distances) was not needed to create full self-driving cars. And that's why their cars instead use a bunch of cameras to monitor the outside world.

Now, I'm not an engineer, but this never made much sense to me. Cameras can only see so far and they certainly can't see at night. So wouldn't laser sensing technology that can see 250-500 meters out — including at night — be greatly preferable when it comes to human safety, even if it costs more?

I'm reminded of what I said to my eye doctor before getting laser eye surgery many years ago: "This is not a transaction where I'm looking to be price sensitive. Get me the absolute best." And that's exactly how I feel when it comes to self-driving cars. I don't care if cameras are pretty good most of the time; I would prefer to have the best.

So which is the best? Damned if I know, but here's an interesting and also hilarious video by YouTuber and engineer Mark Rober where he compares the two technologies: cameras (i.e. Tesla) vs. LiDAR. I won't spoil it for all of you, but his last test is the "Wile E. Coyote test" and it's awesome.

At the time of writing this post, the video already has more than 11 million views and it seems to have been incredibly helpful to Luminar's stock price:

I had coffee this morning with an engineer who is going back to business school in order to segue into real estate development. This is a fairly typical journey. Lots of people come into development from a related discipline. In my case, it was architecture (even though I never practiced architecture). It was also the case when I went to Rotman that something like a third of the class had a background in some sort of science or engineering field.

However, one thing I did mention this morning was that he will likely find that he will need to unlearn certain things as he moves forward. Every discipline tends to indoctrinate us with a certain way of thinking about the world. Lawyers tend to be a certain way. Engineers tend to be a certain way. And architects tend to be a certain way.

In my case, I found that architecture school taught me to be, among other things, an intense perfectionist. The modus operandi in design studios is that your project is never ever complete. The more you work on it, the better it will become. And as a result, you should feel a deep onus to work on it as much as humanly possible. But in business, this isn't practical. In the vast majority of cases, speed over perfection will serve you better.

I believe wholeheartedly in multi-disciplinary backgrounds, and maybe this is one of the reasons why. It shows you what you should unlearn. What would you say your biases are?
