Not that these technologies don't have anything to bring, but any discussion that still presupposes that cars/trucks(/planes) (as we know them) still have a future is (mostly) a waste of time.

P.S.: The article mentions the "normal error-checking processes of society"... but what makes them so sure cults aren't part of them ?

It's not like society is particularly good about it either, immune from groupthink (see the issue above) - and who do you think is more likely to kick-start a strong enough alternative ?

(Or they are just sad about all the failures ? But it's questionable that the "process" can work (with all its vivacity) without the "failures"...)
