When the computer is good enough that you haven't had to do any driving in the past 3 months, how much are you really going to be paying attention when something goes wrong?
I'd suggest that once this is consumer-ready, the vast majority of "something goes wrong" scenarios where the car doesn't know what to do would fall into one of two categories:
These things'll never, ever be perfect. They will almost undoubtedly reach a point where they're at least an order of magnitude safer than humans, though. That'll be more than good enough for most people.
Those of us who don't live in cities have been driving fine at night without streetlights forever.
Of course, y'all have significantly more accidents than us mollycoddled city slickers, so you may want to reconsider the use of "fine" in this context.
Damned if you obviously copy Apple, damned if you intentionally go with the inferior solution that Apple rejected.
that does not work _at_all_ if you have a halfway decent content- and tracking-blocker installed
...well, once you've blocked the content, and once you've blocked the tracking, there's not much left to work with, yeah?
Monetary policy is all but moot for people who simply have no capital to spare. Deflationary currency isn't going to do any better than inflationary currency + investment on this point.
The other thing -- and I am surprised you did not touch on this -- is that a deflationary currency is anti-consumerism. Why buy something when saving that money makes it worth more in a year or ten?
I touch very greatly on this. It's anti-consumerism and anti-investment. Why waste money upgrading or properly repairing the combine in the field when you're better off just letting that money enrich itself over time? Sure, you might get a better crop yield, but then again, you're sure to see your money increase in value, so just kinda run things by the skin of your teeth, and only spend when it's absolutely, entirely necessary.
You end up with a society where the people who can afford to not produce do just that: they live entirely off the fact that their money is going to be worth more tomorrow than it is today. Their lives are enriched by very literally doing nothing with the enormous wealth they have, whereas the people who actually are doing the work see their incomes steadily drop and reap virtually no deflationary benefit, owing to their near total lack of wealth.
A deflationary monetary policy, by its very definition, rewards people for hoarding their wealth instead of investing it in a productive fashion. Classes calcify; the wealthy take no risks and become wealthier as a result, and the poor have to make ends meet with an ever shrinking portion of the total wealth of the society, because the majority of money is locked away and earning value for itself. There is ample historical precedent for this. It almost always ended badly.
And with bitcoin, you keep your own coins, you don't deposit them in a fractional reserve bank that uses it to stimulate business.
...and yet we have all these exchanges for Bitcoin cropping up everywhere. It's almost as if there's inherent and significant value in institutionalized finance even in the Bitcoin world. It's almost as if banks actually provide an array of useful services that people are willing to pay good money for. As if most people acknowledge that yes, I could simply carry a wad of legal tender around on my person, but this bank over here enables me to transact my business so much easier and in so many ways. Odd.
This is what the Earth needs. We cannot go on consuming our childrens' futures. We must end our senseless consumption in the name of "progress" or the Earth will lose enough of its ecological web that we can no longer survive. Some say it is already too late. I maintain there is hope but we must adopt a more sustainable civilization or we will perish.
Oh wait, so your recommended vector to ecological stability is through a generations-long process of grinding productivity down via deflationary monetary policy? That is inane. After singing praises--lower costs for food! Greater saving! Helps the poor save!--you're now going to turn right around and sing the praises of how it naturally destroys productivity.
There exist far more direct, far more effective, and--despite the fact that we currently have a snowball's chance of getting them enacted--far more realistic and implementable ways to improve and protect the ecology of our planet than convincing everyone to throw sand in the gears until things eventually fall apart.
At the end of the day, the biology of deflation means our money more closely matched natural systems governed by scarcity.
You wish to align to a state of nature. On this, I will defer to Thomas Hobbes:
"In such condition there is no place for industry, because the fruit thereof is uncertain, and consequently, not culture of the earth, no navigation, nor the use of commodities that may be imported by sea, no commodious building, no instruments of moving and removing such things as require much force, no knowledge of the face of the earth, no account of time, no arts, no letters, no society, and which is worst of all, continual fear and danger of violent death, and the life of man, solitary, poor, nasty, brutish, and short."
The life of man, solitary, poor, nasty, brutish, and short. This is the direction you think we should move.
