HAL-9000 murdered the crew because he was ordered to conceal information but did not know how to lie. We know from TFA that it is really easy to train AI's to lie. Thus, a HAL-9000 problem is unlikely. It is too easy for AI's to lie and that leads to different sorts of problems.

A well known solution to the charging time problem is battery swapping. There are solvable but real issues with battery swapping "in the wild" but these don't really apply in this application.

1. Batteries are heavy so moving them around requires something like a fork lift. Where are you going to find one of those in an Amazon warehouse? Oh, wait..
2. Cars come in a wide range of shapes related to reducing aerodynamic drag. Working with those different ways to accessing differing shaped batteries is a real problem. Forklifts are shaped pretty much like bricks and Amazon has total control.
3. "In the wild", batteries come from who knows who and there is a real risk that the owner of a brand new EV swaps his/her brand new battery for one that is about to die. In an Amazon warehouse, the forklifts are owned by Amazon and, well, that's all

Why is 4.0 special? Later version in the line exist up to 6.0 There are even later versions whose naming conventions suggest more radical changes.

Reading code written in an an unfamiliar language is annoying but it is still much easier than reading code that produced by an unknown machine transform. The latter cannot even be trusted to be correct. At best machine transforms can be useful to make a human doing the conversions more productive. Even then, the transforms are likely to contain mistakes and be under documented in the quest for maximum productivity.

That is actually not established. We don't have the ability to train two humans with exactly the same data and algorithms. Those neural nets are already being trained in the womb and they continue to train in other things while you are trying to train them in a particular task. If you trained an AI with non-topical data and then started doing the topical training, you would probably get varying results too.

Will we? I mean we already "have" BTRFS but it still isn't considered fully stable 14 years after it was added to the kernel.

Single use batteries are not supposed to go to the landfill either. All batteries, rechargeable or not, are e-waste.

Adblockers only do so much. My FB feed is swamped with worthless sponsored posts. Adblock does nothing to clean out that manure.

Football fields is not consistent. Where the word "lorry" is commonly used, a "Football field" is a different size (and different sport) than an American Football field. Down Under, it isn't even one size.

The grammar in both TFS and TFA is confusing but that is really what is going on. Only two companies had orders for 3nm from TSMC: Apple and Intel. Intel postponed their order. That meant available capacity for other customers in queue but there weren't any so TSMC will just reduce production.

More generously, perhaps there are other customers who like to 3nm chips made but the Intel delay isn't long enough for them for another customer to slide in.

If you have a clear spec, sure. But if the source and developers are missing, I think it is likely that the requirements are also AWOL or perhaps just wrong. In the latter case, the original developers, who had much better information at their disposal, adapted the code so that it worked but never updated the spec.

I can think of a few more options.

• It works but is difficult to produce reliably. Good enough for lab experiment. No mass production
• It works and can be made reliably but is fragile. Can't survive the real world
• It works, is robust but its superconductive capability is fussy about environmental conditions. Room temperature and pressure, sure, but which room? Doesn't work in the real world

It doesn't seem to have the unobtainium problem so that is at least promising.

I did. I could reliably get non-stop flights from San Jose to STL for $200 at Christmas time in the mid-90's. That works out to about $357 in today's dollars. Good luck getting a flight like that for double that price today.

Citation please.

I was flying in the mid 90's. Current economy flights between the West coast and mid-west are about 3-4x what they were back then. Granted, there is inflation but up until recently it was pretty low. There is no way in hell business class is cheaper than economy back then and economy seats were much spacious then. If you back far enough into the 80's you get into the pre-deregulation era which is a different world but the packed in like sardines trend is long past that point.
