Once food making machines become a mature technology, they'll be much *better* than human employees. A machine doesn't have enough imagination to get tired, distracted or forget things. If it's programmed to cook something for 178 seconds, that's exactly how long it gets cooked for, every single time.
Putting millions of people out of work is either horrible or great, depending on whether or not we've done basic income yet.
The only reason the power wall could make sense for individuals is if the electric company overcharges the customer or doesn't pay them enough for the solar power the customer sells back to the grid.
They do. Australian electricity is fairly expensive and we get pennies for generated solar, so charging your battery during the day when you're not home and using that power at peak time in the evening makes sense, and it will make more sense as the price of solar and batteries comes down.
The power companies raise rates and cut feed-in tariffs to maintain their profits, which makes more people buy solar and batteries, which means more rate rises and tariff cuts, which means more solar and batteries.
We could transition to a smart grid, where power is valued depending on how far it needs to be carried from generator to consumer due to the reduced load on the grid. Alternatively, the power companies could spin merrily in their death spiral while crying for government to save them, which seems the most likely possibility.
Electric car incentives are because electric cars are currently significantly more expensive to manufacture. The incentives bring the cost to the buyer down closer to the price of a gas car.
Nobody says, "I really want a car that's louder, smellier, and helps fund Saudi Arabia!" They buy gas because it's cheaper. So far. Another 5-10 years and electric cars will get down to gas's price point, on top of being much cheaper to run. Reaching that point sooner is the point of electric car incentives.
A new way of encrypting things that has a third key? Sure, but why not wish for world peace and a Star Trek style warp drive while you're at it?
Things that don't currently exist aren't a reasonable solution, either. No matter how often Congress demands them.
He's arguing against raising the minimum wage because it's pricing human employees out of the market. Okay, so what's the plan in 5 years when the machines cost half as much? Or 5 years after that, when the machines cost half as much again? Are we going to lower the minimum wage to one dollar an hour?
More than that, if minimum wage employees get pay cuts and job losses like he is threatening... who does he think will have the money to buy his robot-made burgers? Cutting the minimum wage means you spend less on payroll, but your customers are somebody else's employees and they got a pay cut too.
The problem with Windows is the way it handles file access.
Under Linux, when you delete a file it's removed from the directory listing, but it's still there on disk. Any program that was using the file continues using the now 'deleted' file.
So an updater can delete a file that's in use and write a new version of the file. Programs that run from that point on use the new file, programs that are still running from before the update keep using the old, deleted file. That's what lets updates quietly run in the background.
Hydrogen is just a stopgap measure, though. You have to use electricity to make the hydrogen, so in ten years when a car battery has 600+ miles range on a 20 minute charge, why bother?
Who wants to build out tens of thousands of hydrogen filling stations only to have them go obsolete within a decade? I can't see a big hydrogen network being built by anybody with any sense, and without that hydrogen cars won't make any headway.
One of the big advantages with battery powered cars is you already *have* electricity. There might not be a rapid charger anywhere near you, but you can still plug it in to a wall outlet overnight. So you can sell electric cars and then build the infrastructure after they start to take off.
Did anyone actually get fired or did they just run the business into the ground?
"Go and get skills" is decent advice to give to an individual, but it doesn't work society-wide.
Where are we going to get 80 million new skilled jobs for all those newly skilled unemployed people?
