Cheap yet ultrapure titanium metal might enable widespread use in industry
Titanium is the ninth most abundant element in the Earth's crust, yet products based on pure titanium are uncommon because it's expensive to remove the oxygen from titanium ore.University of Tokyo (Phys.org)

(and that goes for all autonomous vehicles, whether subways, trains, cars or tractors...)

in reply to Yogthos • • •Yes, I know, and environment recognition can be done in a more... flexible way, but we need to look at what we call AI.
For example, automatic parking on cars inevitably has an adaptive component, but we can be sure that it won't do anything stupid either (and for example, Tesla chose to go with full machine learning on it, and they gives much worse results than the competition).
Agriculture was already using semi-automated vehicles, notably via very precise GNSS positioning, for example (and besides, I'm not convinced by a tractor without a cockpit, having a supervisor seems to me to be preferable no matter what level of automation you reach, except in some special cases (subways in particular, since they have a very controlled environment, but then you don’t need any kind of AI)).
In short, AI as it is generally referred to today is not relevant here, in my opinion. Then again, maybe it's a completely different type of AI that's relevant in this case, but that's not really the point (and it's been around a lot longer, and most people don’t complain about it).
That said, I interpreted your message as “these new AIs can have a relevant use like here", but perhaps it meant “there are other types of AIs that shouldn't be mixed up with the ones they're trying to sell us everywhere, and which aren't to be thrown away”, in which case we agree and I'm sorry for the off-topic.
