Those extra journeys can be minimized with decent routing software. Even if it's as simple as ending up at B, then going directly to the nearest customer waiting for a ride. And fwiw, if Tesla gets their robotaxi stuff working, their 2

I think the main issue is that it takes a lot of engineering from the ground up to make an electric car with good range and performance. Maybe if batteries get significantly better, then conversions will get more popular.

Luckily, given the Bernstein decision saying source code is protected speech, Github's hosting probably isn't so vulnerable.

This is only loosely related but I thought you might be interested in a new paper, just described[1] by Sabine Hossenfelder. They started with the assumption of a multiverse, and said that we're most likely to find ourselves in a unive

So just under 100% more likely, i.e. twice as likely? That's an underestimate. Only 9% of rape victims are men. https://www.humboldt.edu/supporting-survivors/educational-re...

Letting users pick the algorithm seems like a good way to give them responsibility. And the article says Bluesky still has a simple subscription feed as the default.

My claim is just that if we see something that seems like an unlikely coincidence, we should look for explanations. Either there's some underlying reason that it isn't a coincidence after all, or there's a reason that no obse

I wouldn't advocate "super-inflated" estimates but within reason, there are long-term benefits if you go about it right. Where I mostly worked, managers cared about deadlines they could tell to external clients, which they re

You can't, not for sure. But this does mean that we shouldn't expect to find gratuitous coincidences. Most likely, the apparent coincidences we observe in physics and cosmology will either be necessary, due to physical relations

by DennisP 2y ago
Here's a counterargument. Let's say there are two possible coincidences, A and B, each with an independent one-in-a-million chance. Coincidence A is necessary for life to emerge, but B is irrelevant. Now let's say there are a

Generally, 10-20 years and 100K-200K miles. The US requires a warranty of 8 years and 100K miles. For newer cars it's hard to tell for sure since the tech has improved significantly in recent years. But even the earlier cars have done

Environmentally, converting coal to natural gas isn't that much of a win. Take methane leaks into account and it might even be worse. It'd be interesting to see the cost per ton CO2e of paying to shut down gas plants as well.

by DennisP 2y ago
Yeah if we did something like this for real, we should make a more realistic estimate of how much of a return the plant owners are really likely to get, instead of just arbitrarily multiplying their investment by two. But while coal is decl

by DennisP 2y ago
The problem is that the risk is still paying off. The coal plants continue to run, and it's not that easy getting the political support to shut them down before the economics make it happen anyway.

by DennisP 2y ago
If I'm reading this right, they just added up the remaining amortized capital cost of the plants, doubled that to give the investors a return, and divided by the amount of CO2 emissions that would be avoided. They don't mention co

Given the context above, does that mean the modern version is no longer "overcomplicated and hard to implement?"

The thing about batteries is that those big discoveries in the lab take a long time to reach the market. By the time they do reach the market, they're just an incremental improvement over all the other big discoveries that are already

And stage 4 melanoma used to mean you'd be dead in a year. I know someone who got diagnosed with it almost a decade ago, got three doses of immunotherapy, and is now cancer-free. Doesn't even have to get scans anymore.

But if you want entities like SpaceX, all those other people have to be able to invest in them. That's not the case today. I think we should loosen up those rules so they can, but that does mean some people who aren't rich or soph

Since investors are forward-looking, I don't think there are many situations where a change that's good for the long-term value of the company will necessarily drive down the share price in the short term. You might drive down

Based on your first sentence, it seems that by "returns" you mean increases in stock price. Given that, I don't think there's a clear dividing line, since investors are always forward-looking. I could see only long-term
