The price you pay for a good or service mostly captures labour costs that went into it.
Depreciation and maintenance costs for a taxi vehicle only account for a small portion of the fare. The taxi driver's wages are the most significant portion. Even then, maintenance and fuel costs also contain significant amounts of labour, such as extraction, manufacturing, transportation and the mechanic's wages.
It's inevitable that automation makes jobs redundant. It has happened throughout the industrial age and continues today. Many computer peripherals are named after jobs that no longer exist.
Automation replaces jobs and makes the prices of the output from these replaced jobs significantly lower. I'd make an educated guess that labour-intensive products see their prices slashed by one or two orders of magnitude when significant new forms of automation come to that production line.
More automation makes more things affordable, and many jobs become obsolete. Simultaneously, the affordability of formerly expensive products makes the demand for those increase, and with it the offer, until labour costs rise to become the most significant portion of the price of these products, as automation always leaves gaps to be filled by relatively-expensive humans.
A concrete example of this is travel. Seventy years ago it was significantly more expensive, labour-intensive, and dangerous to travel by commercial airline. Two hundred years ago, during the age of sail, it was even more time-consuming, labour-intensive and risky to travel by sailboat. Long-distance travel was never as affordable as it is today, when people on modest wages travel frequently to exotic destinations by air.
In conclusion, I present the argument that automation is always a net good, and our general quality of life will improve thanks to the current wave of automation. As always, the fears of massive long-term unemployment will again turn out to be unjustified.
Fantastic post!
Add to this that hydrogen molecules diffuse through pretty much every material, making tanks that hold it brittle over time, prone to failure.
Hydrogen wants to react with oxygen extremely badly. The atmosphere has a lot of oxygen, and with a bit of heat, any volume of hydrogen that gets in contact with atmospheric oxygen will combust in an explosive way.
I don't want to be among the people who pioneer travel in hydrogen-propelled vehicles. I would have to see it operating safely at a commercial scale for a decade to even consider boarding one.
How is your message tagged Troll? There is a large contingent of people here who are ideologically compromised.
What you explain here is exactly what I have been saying about covid since I looked at the numbers: it was less of a threat than the measures to contain it warranted. Putting the entire world in quarantine and stopping most economic activity for years was not justified to give a few extra years of life at best to the oldest and most frail people among us. The cost was too high for the benefit. But the pathetic Zeitgeist in the world right now can be personified by a neurotic old schoolmarm: the spirit of a gyno-gerontocracy.
Your wife's father was old. Evidence that the covid vaccine caused his dementia has to be a lot stronger than developing symptoms three days after taking it, given the large-scale vaccination trials and subsequent mass administration across the world, that didn't lead to widespread dementia. I don't expect that you'll use conspiracy theories to try to explain this, because you seem to be intellectually honest and respect data and evidence.
Please go away.
