You should see how hard it is to import any car that is not also produced for the US market.

I can't find a monetary breakdown of online vs. other, but by total advertising costs, I see 1.5%. So if online is not dominant I agree that they are high but close, maybe within t…

To address the cumulative effect, this is the same as the sun. There is a balance of heat radiant on the earth and then earth radiates to space. The amount coming to earth is set b…

Using total energy consumption (not just electricity) and redoing the calculation using entire incident solar flux, I get that they are within a factor of 4 of each other. I agree …

I believe it is both. The CO2 helps to trap more of what the earth receives from the sun (primarily what is talked about with global warming), but our energy use is also staggering…

There is already legislation about acceleration, it falls under e.g. 'exhibition of speed' and everyone one of these modern EVs is able to violate it (and do regularly, afaict).

It's not just inconvenient, it's inconvenient enough to almost say you can't do it. I believe there is a firm lockout period of 2 years (so no 'new' cars can be imported). And then…

Apologies for being pedantic: yes, change is coming, but certainly not faster than that brought on by a giant asteroid impact or major eruption. I only mention this as I feel exagg…

One way or another the company's obligations are down. Company revenue is ~$200B/yr so they will easily take advantage of the full tax exemption, which you could then think of as p…

This replacement schedule is what's creating the fungibility of the cloud.

Highly agree. Their interface is not intuitive. If it were then I (with my decades of computer experience) would be able to use an iphone after having never used one. The few times…

I think this is more insightful, or at least interesting, than replies are giving credit. Sure, you know your temperature from the thermometer at your house, but how do you measure…

I was surprised, but this calculation checks out. Wild. This really points to the scale of influence that large companies have, especially considering this is < 0.1% of typical hou…

My point is the ROI of investments in those systems is much higher than trying to improve car infrastructure. And, necessarily, crashes and costs of cars are reduced along the way.…

What are the additional costs of cars and their infrastructure when there are more efficient options for transportation?

I think a lot of the answer is 'chaos'. Most nontrivial systems are chaotic (generically, iirc more than 3 unconstrained d.o.f. + non-linearity) and most chaotic systems quickly er…

Speaking of corrections, it appears that homophones are a type of homonym, https://en.wikipedia.org/wiki/Homonym

Reproduced your calculation on the 1 million miles, it's surprising but checks out. Then consider how many miles of road we have already made and how much we continue to make to su…

I believe if you compare the overall efficiency (including food production, transport, storage vs. battery production and electricity), e-bikes are in fact more efficient than trad…

It is more than the average lifetime peak retirement savings in the US (which will be in multiple accounts, generally).

All investments have risk. This is one of the risks associated with meager yields - very rare but possible wipe out. If depositors were always guaranteed then what would prevent hi…

I think this is the point. In the example given, if you introduce a sqrt, then the argument becomes much weaker already. The dispatch is comparable to the computation time. I'm rem…

Yes, I'm aware, but I personally am in favor of pressing the issue. Though I don't know the details here, in some cases of first diagnosis there will be hospital admission with 72 …
