With seemingly so much happening in the world these days -- everything from COVID to climate change -- it is perhaps easy to feel a little discouraged about the current state of affairs. But I am an optimist. And as I mentioned on Twitter a few weeks ago, I haven't been this excited about the future of tech and the internet in a long time.

We are seeing the auto industry quickly transition to electric vehicles (though, in my opinion, not driving at all is still better for our cities than driving something that is electric). Norway has created the world's first ever zero emission, autonomous cargo ship. And LIDAR vision systems are looking pretty promising as one of the technologies that will ultimately power fully autonomous vehicles.

I believe in the resiliency of cities and, as I have been arguing on this blog all throughout COVID, I think the claims about the demise of our cities have been greatly exaggerated. In fact, I think this pandemic has forced us rethink a lot of things about our urban environments, including how we allocate and use our public spaces (think patios). Some of these changes have been for the better and they're not going to go away.

I think the benefits of working in close proximity to others are too great to have everyone working remotely. Yes, we have learned that decentralization is possible. But there's an overwhelming amount of research telling us that we're all more innovative and productive when we cluster together in cities and in offices.

I have been back in the office almost 100% of the time since it has been possible to do that. And I am much happier and more productive as a result. There's also research suggesting that there are

Luminar Technologies, which is an autonomous vehicle technology company that I have written about before, just hosted its first ever "Studio Day" in New York City this week. And at the event they announced two new technologies.

The first is called Iris, which is a small lidar device that is intended to be integrated into regular consumer production vehicles -- on the roof just above the windshield. And supposedly the company is on track to have these into full production and available to their OEM partners by the end of next year (2022).

The second technology is something that they are calling Blade, which is a lidar system that can offer a 360 degree field of vision and is intended for use in robo-taxis, trucks, and other consumer vehicles. It's called Blade because it's kind of like a blade that wraps around the tops of these vehicles.

We've been talking about autonomous vehicles for what seems like a long time. And it is now clear that this is not an easy problem to solve. But from what I have read, lidar seems like the promising technology and something that will become necessary for full autonomy. So I am now long $LAZR. Whether this is the right move is still to be determined.
