Lots of interesting news today

The more I think about it, the dumber it seems. Obviously this a publicity stunt, not a science experiment, but if the barrels are sealed, the vacuum is on the wood, not the liquid. And if they are not sealed, it would have no effect.

For the amount of time they did it…I don’t see how it had an effect at all. There’s a reason for the aging process and pressure/temp changes are the primary reason for that…but it certainly wasn’t replicated with the flight. Doing a little more digging, looks like this flight was a year in the making and was for nothing more than publicity.

The thing I can't wrap my head around is liability and the potential for accidents that are pretty much all non-trivial.
An accident between two cars on the road sucks for them and anybody in a 20-30 foot radius.
An accident between two flying vehicle sucks for anything in an unknown space underneath them.

Not to mention, having a sudden impact and falling out of the sky tends to hurt more for both parties.

You'd almost have to have some beyond Tesla level self driving functions baked in to even have a chance at making it practical.

I could see something like that becoming reality MANY years from now. Like 50-100 years.

The only way all of this works is if it is all 100% automated. The hard part isn't the flying or landing, it's avoiding the other idiots who are not flying or landing like they are supposed to.

If you accept complete automation its a lot closer. But that is a giant IF.

I was referring to flying cars automatically controlled so they don't crash into each other. No way that happens in less than 50 years.
 
Dudes! Star Wars has this covered,it's old news.
Duh, floating traffic lights!

I've said this for 10 years about the self driving cars. The only way I would trust it is if EVERYONE was automated. One dumbass can throw the whole thing off.

Or you create special roads or lanes where only full automated cars can drive.

That is currently on commercial aircraft, atleast when using auto-pilot.

But, could you imagine all the air traffic control towers that would be needed if there were that many more people in the sky?
 
In regards to automated vehicles, we have been involved with auto truck driving tests on some of the toll roads. Usually the tests involve 3 tractor trailers in a "platoon". Some of the tests included emergency stops etc. Minimum distances between the trucks were around 20ft if I recall correctly and the brake tests were done with only the lead truck "deciding" when to stop, meaning the 2nd and 3rd truck had to "read" the distance and then apply brakes etc. These were done back in 2019 so I'm assuming the tech has only gotten better.

All done on a controlled access portion with no other vehicles. Tests went well and and I believe they are going to perform more tests in the immediate future. IIRC they used the latest volvo trucks.

The thing is future automated systems can use way more than just optics and passive sensing of other vehicles. The most common approach to convoy situations is that all the vehicles communicate via Wifi-esque RF, so when lead vehicle says "stop" they all know within a millisecond. No need to guess what the lead vehicle is doing.
In a fully automated network of vehicles they can all be talking to one another all the time. If somebody goes bad with one, they all know and can respond appropriately way faster than a human could.

This model works great as long as everybody is on the same network....

The 'smart' automated vehicles will obviously have to deal with 'dumb' vehicles for MANY years. I hope to still have one of them. 40 years from now when I am 87 yrs old I will still be driving my 67 yr old Dodge Ram oil burning black smoke belching truck. They will have to avoid me. Look out!

Bingo.
I work with guys designing machine learning algorithms for automated vehicles to work with unpredictable things and so-called "zero-trial learning."
My personal goal is to be the asshole makes their job hard.

This is the part I'm not so sure about, and where the human brain (typically) outperforms AI.

This is why it takes 100% automation. No variables. If everything is under control of the system, then everything is predictable. AI is really good at that... much better than humans. Humans are great at unpredictable things and terrible when precision and repeatability, or even making predictions, is needed.
