If we imagine a near-future scenario - a battery powered house heated with heat pumps, driving an electric car, during central European foggy winter, which tends to last for about a week at a time. Let's say they use 60kWh/day. We're looking at $100k just for the batteries and installation, even assuming electricity comes free. In ~15-20 years, the batteries reach their recommended cycle life, requiring a choice of another $100k or accepting that what used to be a 3-day storage becomes 2-day
This is not some "extreme situation". It's a completely predictable scenario that recurs with near 100% probability every single year. Then there are places like Ganges river, Bangladesh or Indonesia, home to hundreds of millions of people, where neither solar, nor wind is viable (and land is scarce)
Why is there no public transport? Because it's losing money due to low ridership. Why is the ridership low? Because people are afraid of dangerous neighborhoods, wackos, homeless and other people of lower castes. Why all of these factors? Because of massive inequalities, rugged individualism, broken healthcare, missing social nets,... Unless that is fixed, the public transport won't be a decent option. Driving everywhere allows people to form a bubble that shields them from daily witnessing the ills of the system
There are two major manufacturing hubs in the world - east Asia and central Europe. Labor costs in manufacturing around the world have equalized to start at around $12/h. Slightly more in automotive. Average wage (whole economy) in Guangdong is ~$10/h. Labor cost in Poland is ~$13/h. The days of labor cost arbitrage are over
One can find cheaper labor, but it's always at the cost of worse infrastructure, missing supply chains or increased shipping costs. This is not pharma or silicon, where value per kilogram makes the cost of shipping is negligible. Manufacturing and assembly of heavy items like cars, trains or construction materials is nearly always near-shored
Adding housing maintenance, heating, water supply, etc. - the entire housing category climbs up to 17.8%. Which sounds like a totally reasonable estimate to me - young people and urbanites pay more, older folks and people in rural or provincial towns pay much less. From my personal experience - housing and related expenses were ~50% of my income while paying down mortgage, down to ~7% after the loan was repaid
the problem - this became an institutionalized modus operandi of Silicon Valley, finance, higher education, IP law, crypto, even real estate - essentially the entire economy of intangible goods and services. As Jim Chanos put in ‘We are in the golden age of fraud’ - lying to investors, public or congress or courts became so normalized that people no longer see any problem with it
No amount of innovation, pivoting or clever engineering could have saved Kodak. They were not flabbergasted at the technological change. The best course of action was to milk the existing market for as long as possible, which is exactly what they did
God/Allah/Nature obviously don't understand disruption, growth mindset and can-do-spirit. facepalm
There are hard physical limitations that no amount of human ingenuity can do anything about. 237kJ/mole is the theoretical minimum of energy required for water electrolysis. energy->electrolysis->energy round-trip efficiency won't exceed 45%, even if everything, from the energy source to the car wheel spinning, is perfectly frictionless and operating at peak theoretical efficiency. No, you cannot use existing gas pipelines for transporting hydrogen.
For passenger cars, EVs today are already better than what physics allow hydrogen cars to ever be.
Cars are not phones, and will never be. American lower class or Chinese middle class are not going to shell out $70k for a new toy every two years. Cars are not going to be made with 60% margins. You cannot wear a car in your pocket to show it off to your relatives or business partners.
Apple's business model, in short - is selling mediocre hardware for premium prices, and mask it with excellent software. Optimizing software to make it 10x better, faster, using less battery - fairly common. For any activity that interfaces with the physical world - forget it - we're tapped out, making 2-5% improvements per year. No amount of refinement will make a $20k econobox sellable for $60k
(also, ironically, LG dropped out of phone business)
Also, the whole claim would really need a citation, and careful parsing of the methodology. 3x difference in a mature industry like car assembly is very unlikely, and requires a very strong proof to back that statement up.
In addition, this figure also includes the "labor share" of top-level management. People focus too much on CEO pay, and neglect the fact it's also C-suites, vice-presidents, board members, and most of the direct and indirect perks they receive. I wouldn't be surprised if the labor share of income to this new nobility increased from low single-digit to double-digit percentage

The benefits of not being a tourist destination
On paper, it's a perfect crypto. Really fast and fee-less transactions, proof of stake avoids the environmental impacts, completely pre-mined, distributed as equitably as you reasonably can, and truly decentralized.
But it has one major flaw - no way to get rich quick. No celebrity hyping it up. Nobody is "in it for the tech", it's all a glorified game of chicken
This filters out bots, fake reviews and low-effort negatives (product is ok, but shipping!)
What's left is man-made reviews that praise what is praiseworthy, and highlight the real drawbacks the products suffer from

The important takeaway is that greener electricity grid will help both the emissions from manufacturing, as well as emissions from usage
On the other hand, there are a lot of good arguments in favor of state ownership - matter of national security, need for redundancy instead of efficiency, it's a commodity and a basic necessity, low margins, large scale leads to financing issues for corporations, chicken-egg problems that state is better at dealing with, the domain is primarily about engineering challenges with branding and management having very limited impact, simple supply chains, cost-cutting may lead to disastrous consequences, etc...
Fun fact - Rudolf Diesel's first engines were running on cooking oil. In fact, many diesel engines can operate on vegetable oils without modifications (not long term though). That sounds odd, but from the perspective of "burn hydrocarbons to generate heat", petrol, diesel, oil, body fat, coal or kerosene are all very similar to each other.
Helicopter money (1) does cause inflation, but the reason that the inflation has been stubbornly low for a decade is precisely because the central banks are forbidden from doing helicopter money

Taking Facebook as an example:
Creating an account, linking Oculus Quest to it and leaving the account dormant - accounts locked en masse.
US account that logs in from Indonesian IPs, never posts anything, likes 5000 random things ranging from a shampoo to a cafe in a small Ohio town, to the new shirts of an Albanian soccer club - in Facebook's view that's a perfectly legitimate account.
As a deterrent against nation states, it's questionable how a billion dollar submarine would handle a swarm of thousands of suicidal drones, at a fraction of the cost of the submarine. The submarine takes years to build, a no-name Chinese factory can pump out thousands of drones in a day.
Imho, the approach of the PLA, betting more on unmanned drones backed by China's industrial capacity, is a more logical evolution of warfare.
