Something like the allwinner A13 is down at the low end of practical. It’s about $1 per chip, wholesale. People have gotten it running on an ATMEGA before. It required a bunch of helper components however, and took 2 hours to boot up.

True, but they weren’t really used much as flying cars till later. I might be wrong on exactly when they moved from military to “rich transport to the race track”, however.

We’ve had flying cars since the 70s, they are called helicopters.

The issue with a flying car for general use, is one of maintenance and safety. If an older car breaks down, it causes a tailback. If a flying car breaks down, it could demolish a school. The higher standards required means higher costs. That means rich people only. The rich use helicopters in exactly that manner.

This is one of the biggest frustrations with nuclear power. The first power plants had issues (mostly due to them being bomb factory designs). We learnt from that, and designed better ones. They never got built. They were swamped in red tape and delays until they died.

Decades later, China comes in and just asks nicely. The designs work fine. China now leads the way, built on research we left to rot.

It’s also worth noting that there is a big difference between a fusion power plant and a fission one. China is doing active research on it, as is the west. There’s quite a friendly rivalry going on. We have also basically cracked fusion now. We just need to scale it up. The only big problem left is the tokamakite issue. The neutron radiation put off by the reaction transmutes the walls. Using radioactive materials as a buffer is an idea I’ve not heard of. I’m curious about the end products. A big selling point of fusion is the lack of long term waste. Putting a fission reaction in there too might lose that benefit.

Most locks don’t really keep people out. They just keep honest people honest. At best, they slow an attacker down and/or make it more obvious.

It lets your phone use the larger screen for satnav. It also reconfigures it to a better setup for driving (bigger buttons and reduced complexity). This also means your phone doesn’t need to be sat in the sun, with its screen lit up for a couple of hours, and so overheating.

My phone no longer even leaves my pocket. It wirelessly links to the entertainment system.

It’s obviously the MAGA crowd. They’ve spent years complaining about electric vehicles. They’ve just escalated that to burning them out. The police need to go have a nice chat with the rolling coal types.

That’s tempting, and not a hideous price either.

The same way your mortgage is backed up by your house. If you default on your mortgage, the bank can take your house in foreclosure.

Rather than sell shares to raise the money, Musk has backed his borrowing with Tesla shares. Basically, if he doesn’t pay back the loan, the banks get the shares. Unlike houses, shares can change value quite quickly. If the value of the loan exceeds the value of the shares, then the banks start to get VERY nervous. They will call in the loans to get what they can, before things get worse. This could crash the share price further, since they will want to offload the shares as soon as possible.

Musk is extremely rich. However, like most extremely rick people, his money is tied up in shares. If Tesla falls fast enough, he could end up owing more than he has in assets. As soon as his creditors pull the plug, he becomes bankrupt.

Do you have a link to that study? I’d be interested to see what the false positive/negative rates were. Those are the big danger of LLMs being used, and why a trained doctor would be needed.

I believe a good doctor, properly focused, will outperform an AI. AI are also still prone to hallucinations, which is extremely bad in medicine. Where they win is against a tired, overworked doctor with too much on his plate.

Where it is useful is as a supplement. An AI can put a lot of seemingly innocuous information together to spot more unusual problems. Rarer conditions can be missed, particularly if they share symptoms with more common problems. An AI that can flag possibilities for the doctor to investigate would be extremely useful.

An AI diagnostic system is a tool for doctors to use, not a replacement.

To an extent. You are still talking 20-40 degree windows, but triangulation is definitely possible. I’m not sure if it’s used like that however.

5g is a lot more capable and flexible compared to older generations. The main one is a massive increase in capacity, for the same frequency allocations. Compounding with this is that it can be directional. This allows several phones to use the exact same channel simultaneously, so long as they are positioned at different angles to the tower.

5g also uses more frequency bands, allowing even more data to be moved around. Unfortunately, 2g has most of the lower frequencies, higher frequencies carry more data, but have less penetration into buildings.

Finally, 5g allows for priority and context awareness. E.g. the police can have their phones prioritised, or VoIP calls given priority over video streaming. It can also trade bandwidth for range. This allows a tower to either reach further to cover a larger area, or focus down, to provide more bandwidth locally.

In theory 5g could have a similar range to 2g. However, that rarely happens. It requires it using the lower frequencies, that 2g currently uses, and well as dropping its data rate to improve range. Most of the time it’s optimised for shorter range, and more towers using higher frequencies. This gives impression of a far smaller range. But give a huge increase is available bandwidth.

I would personally add a small amount of slack for bad taste satire (we were all young idiots at some point), but basically agree. Any signs of the other points, and that slack is gone, however.

I was mostly curious if the OP was acting in bad faith, or a useful idiot that could be reasoned with.

History doesn’t repeat itself, but it does rhyme. Musk isn’t a member of the Nazi party. He does hold a lot of important views in common with them, however. He also associates with people who fit most of the rest.

What percentage do you think is needed before calling someone a Nazi?

It works on frogs. The force is distributed over the whole body, so it’s no worse than gravity is on our bodies.

I disagree. The human body is mostly water. Water is slightly diamagnetic. Therefore, a sufficiently strong magnet is capable of levitating a human body off the ground.

Magnets can definitely have an effect, just not at puny neodymium magnet levels!

Interestingly, some lights are set up to deliberately slow down speeders. If you are above the speed limit, they turn red, just to slow things back down. Unfortunately, most of the people involved never put cause and effect together.

That’s part of the reason a moon base could be viable. The sun outputs a reasonable amount of helium 3, which is great for fusion reactions. Unfortunately it tends to sit at the top of our atmosphere and get blown away again. On the moon, it gets captured by the dust in collectable quantities.

I never said it wasn’t useful, just a very low efficiency reactor. Then again, if it was better, it would burn out faster, which would be bad for life on earth.
