If you live in a city where it is possible to live without a car, a smaller percentage of the population drives, thus you don’t have to be around as many drivers per capita, so the chances of encountering someone like this are lower.

Probably because they don’t have to spend as much time around idiots who decide to do this sort of thing.

I can’t speak to the superconducting potions of this comment, but the general computing information is mostly correct.

Switching losses are a result of capacitance in the circuit. These capacitances aren’t going anywhere in transistors made from semiconductors. Additionally, even when a transistor is on it has some resistance, which of course creates heat whenever a current moves through that transistor. Leakage current also generates waste heat.

I could see room temperature super conductors being useful as replacements for bus lines in a digital circuit, but this wouldn’t eliminate the heat in the circuit. Most of the heat is created in the transistor junctions, so the effect would be very minimal if even noticeable.

Doomers want to justify their inaction by pretending that nothing can be done.

What’s better for climate change is less cars on the road, not underground roads. If we are going to be digging these expensive tunnels in every city they should be for subway systems. That would be a substantially better use of the funds and would be a good step towards reducing the emissions of a city. This is all assuming that we stop subsidizing car ownership so heavily of course.

The entire process of building and repairing roads is pretty carbon intensive due to the amount of concrete involved.

Unfortunately they’ll never be ready for it. The good news is that dangerous cycling lanes like these aren’t the only option. We should be investing in safe cycling infrastructure.

This is generally the thought process that Marxists have. The USSR definitely wasn’t perfect, but it is the first real example that the proletariat was capable of uniting and other throwing the capitalist system. The USSR is fantastic to study to try and determine why it failed. Similarly China is a great resource to study to understand how capitalism can be re-established from within the party.

Most modern communist groups actively engaging in an attempt at revolution were inspired by the Chinese revolution and the cultural revolution that came after it, but none of them are trying to recreate the USSR or China because as we can clearly see those states failed to maintain a socialist character.

A lot of these cars are starting to get massive touch screens too. I’m looking at buying a Prius and several of the trims have a 12 inch touch screen. Why would I ever need that as a driver? Why would I ever possibly want that? Pedestrian and cyclist deaths keep skyrocketing and we continue to out these massive screens in cars that in many cases can’t be turned off. Lawmakers really need to make auto manufacturers responsible for the part they are playing in enabling distracted driving.

Phoenix is still one of the fastest growing cities in the US. I can’t imagine that the homes these people are buying are appreciating assets as a result of climate change. A lot of people are going to be completely fucked financially whenever the climate eventually forces move and it turns out they have just been lighting tens of thousands of dollars on fire.

It is absolutely bonkers to me that people still aren’t considering this sort of thing whenever they choose to move to a new city.

It’s mostly bullshit. Certain types of emissions create particles that reflect sunlight away from the earth, thus masking some of the warming that we have created through green house gas emissions. Banning sulphur emissions isn’t the cause of the problem, greenhouse gasses are. Banning sulphur just made our observed warming closer to what our actual warming is.

You’ll find people making the same claims about transitioning to electric cars accelerating warming since cars produce similar particles. It’s just maintain the status quo bullshit passively enabling the continuation of oil and gas. The solution isn’t to keep burning certain types of fuel because it masks our warming. Obviously the solution is to stop producing as much greenhouse gas as we possibly can.

Whenever I was attempting to house shop in my city I couldn’t find anything that was livable for less than $400k. I grew up very poor so I’m not being hyperbolic whenever I say “livable”. I was not looking for anything glamorous. There were houses that should have been condemned going for $350k. This was in a “medium” cost of living area. I couldn’t even imagine what it would cost to buy in a high cost of living area.

Not only that, they despise leftist movements that call modern China what it is. Revisionist.

They hate Khrushchev while embracing the same bankrupt ideology that he pushed, but only whoever it’s in one of the countries that currently claim to be socialist. The social imperialism of the USSR was replaced by the social imperialism of Deng’s China and that was a good thing in their mind.

Also, for those of us who live in cities and have street parking only, not having a reliable place to charge is kind of a deal breaker. I’d love a cheap reliable EV. I think it’s an absolute shame, and a missed opportunity that the new Prius wasn’t an EV, but even if it were I don’t think I could buy one without having somewhere to charge it.
