It can still be optimal because some activity A might provide more utility at 10% utilization rate than activity B at 100% utilization rate . Otherwise shared cars would be vastly superior to individual owned cars and same for houses in which 2 or 3 families live in different shifts ... we actually had that before in some areas in early stages of the industrialisation.

He could always just rent PCs usage time from anyone if he wants more RAM. Maybe using a sort of "token" system to calculate the remuneration?

I'd list it as "Non-Development certain", but objectively you might be right.

your page is more optimistic about KSP2 though -- sadly I think wrongly.

Take a look at indoorco2map.com and you will find plenty of places in Germany with bad air measured in a crowd data collection effort. Most notably doctor‘s offices are often very bad. Many supermarkets too. Schools are not well measurable this way but academic research shows they often are at 2000-3000 ppm or even higher. (Disclaimer: I built the website/App)

It's good to see more money flowing towards this totally underfunded area. However I think it's an odd choice of them to focus on filtration, UV-inactivation and other things and at least from the wording on the website not on ventilation, which they sort of assume as given. They also seem to be way very focused on product development rather than awareness, public policy and lobbying. This is a typical techno-fix approach for an area where existing technologies already exist and are just held back by all types of different market failures (hard to estabilish causality, low salience, needs to be done at large scale, concentrated costs but dispersed benefits, lack of information etc.). In some way it's like funding Direct Air Capture instead of Solar & Wind but in a fictional world where Solar and Wind are already as cheap as today but have a buildout like 20 years ago.

Anyone can already buy those certificates - but as its an artificial market where rules can be changed politically it's actually way more resistant to such things than regular markets, so if those hedge funds feel like they want to lose some billions they can certainly do that. There is a large enough stockpile of certificates + leeway when to submit them that any short term market squeeze will just be dealt with politically.

I do think even the most amateur of amateurs would be able to recognize instantly that a chess board with 64 pieces on it is a invalid game state.

you can get a ESP32 and a CO2-Sensor, easiest would be to use a development kit like a m5-stickC and the Sensirion SCD41 and with some small arduino scripts you are good to go to send the data via WLAN or BLE for something like 70€. Can be even cheaper if you don't use a development kit but it makes things a lot easier and the small display helps with debugging.

I don't know if it's been the first time in fiction where that concept was described but in Heinleins "The Moon is a harsh Mistress" this was what the Moon Colonists did.

21 reactors under construction even with a short build time of 7 years is just 3 finished per year, and with China having ~15x the population of Germany that would amount to 0,2 reactors finishing per year in Germany. Multiplied with 1,4 GW that would add ~0,3 GW capacity resulting in about 2,5 TWh additional electricity generated per year which is 0,5% of annual current german demand. Do that for 20 years and you'd be at 10% of current electricity demand or about 5-7% of the demand in 20 years from now - or in other words micro-optimisation.
