Sounds like they fucked up training the AI then. For a user it doesn't matter whether the AI is designed poorly or trained poorly, it's behaving poorly.

Probably way better and way more expensive.

The Wikipedia article seems to say something similar happened, but in a different way.

A reasonable length survey will never "paint a full picture". Maybe what they're trying to show is that there are a lot more people who value walkability more than is currently assumed. In most of the US you can either chose a super high density walkable area in a condo tower or a house in a car based suburb. It's possible to design neighborhoods that are walkable and can provide a reasonable amount of private outdoor space, and what this shows is people would be willing to pay for it!

What's the point if they still have AMD, Intel, Nvidia, Qualcomm, etc. chips on them?

Yeah the current challenge with searching is if no one has subscribed to a magazine or user on another instance, you have to search the exact name@domain to get it to show up. Ideally Kbin instances would implement a user bot that subscribes to all the users and communities it can scrape from all federated instances until this search limitation is fixed.

I'm a sucker for any connector that has a nice solid spring load mechanism that pops into place when properly connected. It should sound like a movie sound effect of a gun being reloaded.

I've also used some really nice quick release steering wheels, like on race cars or racing sims, where they have a spline connector with a tight fit and a good spring load.

They may be Californian but they're still conservative. They've got Bible verses on their cups. They're a for profit business. They think it will help their revenue, since they know more people hate masks than will leave if there are no masks.

They're edible if you get them "well done". Then they're like rectangular potato chips.

The carbon free rock is replacing limestone in the manufacturing process, not the sand. Sand is added to cement, along with rocks and other aggregates, to form concrete.

From what I can tell, the way this might be bad is that the carbon free rock may not exist in significant quantity. If it does, it will be mined in the same way as limestone, so that's just a wash not a bad thing. If the rock they need doesn't really exist they have to buy it from someone else who makes it from readily available materials. In that case, it could be green washing, where the company can claim "our process doesn't release much carbon compared to the traditional process" but in reality the total carbon released to create the cement - from mining to processing to pouring - could be similar.

Having multiple, semisolated compartments in a Hyperloop train is entirely reasonable. There's definitely room in a traincar for the occupants of a compartment that's on fire to move to another compartment for emergency purposes.

Evacuation points would be defined every so often (say every few miles) such that the train could come to an emergency stop within one, seal doors on each side and let air in. This would take a few minutes, but so does landing a plane or stopping a high speed train.

Bottom line is that fire safety is, to me at least, an entirely solvable problem. The biggest problem with Hyperloop, I think, is that given the materials for the vacuum sealed tube and the energy required to hold that vacuum, it is just so unlikely to be more efficient than a maglev. For medium distance travel, even standard high speed rail is good enough to replace planes, so we don't need the extra speed for ~500 mile distances. For longer distances where high speed rail is super slow or impossible, such as across continents and oceans the cost of building the vacuum tube will be so costly that it would take something like a complete ban of non-renewable fuels in aircraft for it to be a consideration. Even then, I think it could end up being cheaper to develop and use renewable fuels for aircraft.

It is much harder for fire to exist without air. There are some self oxidizing fires, but it should be relatively easy to avoid those materials. For fires inside the vehicle, there are some existing fire protection protocols that could be followed. There have been fires on the International Space Station and they couldn't exactly run outside either.
