Walkmans had no lock in: they played the same tapes as every other device, you could plug the same headphones, etc. Same goes with every shoes or clothes brand.

It's totally different with iPhones: they have their own group discussion app, proprietary AirDrop file transfer, their own apps, etc. This enables lock in via the network effect.

You're absolutely right. The ones who benefit from our children should be the ones responsible for those costs. We can start with guaranteed maternal and paternal leave, childcare for working families, and guaranteed healthcare so that they grow up happy, healthy, and ready to make positive contributions to society.

Here's another concrete proposal: eliminate inheritance. Instead everything goes to the state and is distributed to every kid that reaches the age of majority either as a lump sum to buy a house, start a business or whatever; or as a pension over a decade or so. By some calculations this would amount to about $300,000 per kid reaching the age of majority. This would prevent the accumulation of wealth but also solve the issue that with the increase in longevity people get their inheritance later and later in life, at a time when they just don't need it anymore.

I know it's way out of the box but it's an interesting thought...

Nordic countries still have to obey the laws of physics.

Heat pumps use different refrigerants depending on the climate of the place where they will be installed. The cold climate heat pumps typically have a refrigerant with a lower boiling point that ones for warmer places.

There is no magical product that isnâ(TM)t available for purchase in the US

If Americans are stuck on the idea that heat pumps just don't work in cold places maybe there is no market for importing the cold climate models. There are a lot of things that are not available or really hard to procure in the USA like small hatchbacks, proper vans, dark chocolate, etc.

You don't need battery swap infrastructure. You can just pull a range extender like the EP Tender. Bonus points: car manufacturers don't need to completely redesign their cars to accommodate a standardized swappable battery; and when unused the range extenders can be used as a grid battery.

Guess that all depends on which corporate account is picking up that $3K plane ticket.

The prices I have seen for a Paris - New-York flight in Concorde in the 1990s are north of $10K. The flight NY - LA flight seems to be of similar duration so $3K seems like a low estimate. Also the decarbonation of air travel is all the rage these days. So right after they manage to scale up to a plane with room for more than a couple of passengers the question is going to be: can they make an electric version? With a useful range?

These people are fragile and do a bad job of learning how to separate their personal lives from their private lives.

So I'm going to assume you meant "do a bad job of learning how to separate their professional lives from their private lives" otherwise your comment makes no sense at all. The question then is does your employer know whether you're a man or a woman? If they do (*) then you're doing just as bad of a job as 'these fragile people'.

(*) Remember your employer also has your social security information, including official first name, and they can cross check that against your appearance.

The theoretical life of NMC lithium battery is 2,000 cycles, but its capacity fades quickly to retain 60% when it runs over 1000 cycles;

So what you're saying is that an NMC battery retains 80% of its capacity after 2000 cycles (the standard definition of a battery lifespan), but that it will have only have 60% of its capacity after half those cycles. Make up your mind.

even the best-known Tesla NCA battery can only maintain 70% of its capacity after 3,000 cycles, while the lithium iron phosphate (LiFePO4) battery will remain 80% after 3,000 cycles.

So lets see what this means for a small-battery Tesla Model 3 that has an EPA-rated range of about 220 miles. Front-loading the capacity loss and multiplying by 3000 cycles gives us a total car mileage of 220 miles * 70% * 3000 = 462 000 miles. Americans have an average yearly mileage of 13476 miles. That means the battery should be good for 34 years of driving! So even when using your own numbers and very pessimistic estimates the battery has a good chance of outliving the car.

"at the end of the car's life can be recycled" that will become more expensive & difficult with the move to structural batteries

Not necessarily ;-) Also it really depends if you are talking about glued structural batteries (Tesla) or blade-style structural batteries which can be dismantled without trouble.
