Bitcoin reward cut in half again, with much less effect than one should expect

Chart of the last year of Bitcoin hashrate

On May 11, a major event took place in the bitcoin world, yet it had no negative effect on the price of the coin and much less effect on mining than it would seem it should. This event is known as the "halving," and it means the reward for mining bitcoins was suddenly cut in half.

Monday 2pm EDT, Zoom Tank on future of Public Roadway Transit

I didn't pick the topic, in spite of having written a bunch on in yesterday, but tomorrow we will do another debate in our "Zoom Tank" on the topic of the good and bad news for roadway public transit.

The main debaters are Jarrett Walker from Human Transit, and Randal O'Toole, the "antiplanner" from Cato Institute who is always full of amazing data.

After the short debate, the four sharks, including yours truly, tear into the debaters and their arguments, and then the audience has a go.

EasyMile develops plan to get back in operation using seatbelts. But is the whole idea of transit stops the mistake?

Earlier I wrote about how EasyMile had to stop operations after a sudden stop in one of their vehicles gave minor injuries to a passenger.

Today they announced their plan to resume operations. It includes seatbelts and education. It's a start, but I wonder if the whole idea of "stops" is the problem. Stops are inherent in the 20th century thinking that surrounds public transit. Big vehicles need to make lots of stops picking up and dropping off passengers. But that's a problem if you expect the vehicle not to start until everybody has their seatbelt on!

Waymo and others resume robocar testing

Everybody shut down testing during the Covid crisis. It's not over but now Waymo and others are getting back on the road, testing vehicles with nobody inside, with one safety driver, and sometimes with two. Yes, delivery and rides are essential services, but what are the issues around this?

Read some thoughts at Forbes's site in Waymo and others resume testing

Justifying lockdowns from a standpoint of defending individual rights

Entrance of new Apple Computer HQ, one of the world's largest office buildings, at 5pm

Many people opposed to lockdowns feel they are an improper state interference with our liberty. Possibly an unconstitutional one, particularly in the case of religious gatherings.

Zoox shows an hour live driving video, impressive and unimpressive

Zoox is the $1B funded startup trying to build a radical design self-driving car. Last week they released a video of an hour long drive through Las Vegas, going through pick-up zones in hotels and the airport. The car does a number of impressive things, but at the same time, showing these things and an hour of driving are only the tip of the iceberg of what you need to do, making the video unimpressive at the same time.

In this new article, I go into what goes on in the video, and what it means.

Would you cruise across the Atlantic rather than fly?

Ready to get on a 10 hour overseas flight, wearing an N95 mask, sharing bathrooms, in the middle seat between two coughing passengers? I didn't think so. With all the idle cruise ships out there, would you sail across the ocean like your grandparents in a private cabin if they followed good virus procedure? 4 days stuck in a room (kinda like now) to prove that your virus test is accurate to the country you're heading to.

Tesla "reverse summon" won't be very exciting, but the eventual consequences are

Last year Tesla released "smart summon" which let you (very slowly) call your car to you from across a parking lot. It was cute but a bit of a dud, as it's not just very useful. Now Elon Musk promises "reverse summon" that will valet park your car for you. But if you have to watch it, it's not going to be very useful either.

Eventually, though, we'll get a robotic valet park that works without supervision. That will be very useful, allowing cheaper parking and better charging. Even today, the basic summon could allow slightly denser parking for cars that have it.

Online self-driving debate and lively panel (including me) Apr 27, 11am PDT

Next Monday, we will be doing an online version of a popular panel session we have done every year at the "Automated Vehicle Summit" -- the oldest self-driving car conference.

In this session we have a speaker propose a controversial idea, and then, a bit like a "shark tank" our panel (myself included) tear into the concepts and discuss them, and the audience asks questions too.

Car Companies Are Making Ventilators, But Ventilator Companies, Hackers And CPAP Companies Are Working Harder

If you read my earlier report on efforts to convert CPAP machines into ventilators with new firmwware the good news is that the feared massive ventilator shortage seems (for now) to have been avoided.

Does pseduo-LIDAR help Tesla or its competitors more?

Tesla doesn't want to use LIDAR. So they are hoping for success in a technique known as pseudo-LIDAR, where you train neural networks to look at images and calculate the distance to everything in the scene, as though you had a LIDAR. It's not here yet, but an interesting question is, should this succeed, is it better for Tesla or for their LIDAR using competitors who already have tons of experience using 3D point clouds?

Covid deaths could change election results: Do more Republican voters die than Democrats?

The projected deaths for Covid-19 in the USA are horrific -- 100,000 to 240,000. Let's hope it's not nearly that bad, but those numbers are enough that they actually could alter the election. Not simply because Covid-19 will be the top issue in the election, but because voters will die.

Starsky Robotics is very open about why their robotruck company died

Recently, Stefan Seltz-Axmacher, the founder of Starsky Robotics -- a startup doing self-driving and remove-driven transport trucks that I advised before they started going -- wrote a detailed and complex blog post about why he feels his company had to shut down. He goes into several issues, including failures of Deep Learning to meet hype, VC desires, strangeness of the trucking industry and lack of love for safety.

In my new article for the Forbes site, I dig into those reasons and whether he's right that nobody else will succeed soon, either.

People are doing huge amounts of videoconferencing during the Covid crisis. The tools keep improving, but there's a great deal that individual participants can do to make the meetings better. They take some effort but it's worth it.
