Why limit it to tracking? Why do we put these powerful machines in the hands of users that we know with certainty will kill themselves and others at a predictable rate and then just ask them nicely not to do harm? The technology required to geofence, speed-regulate, and otherwise control where, when, and how fast cars can go already exists. Why aren't we using it? We don't need fully autonomous cars. There are all ki…

Good point but could get tricky for edge cases. Medical emergencies where every second counts for example or escaping violence.

Put appropriate limiters in the vehicles, with a button to disengage all the limits that also notifies the police that you have done so, so that they can decide whether they need to come help, whether (as they later review the case) there was appropriate cause, &c.

I think the OP is taking about beef and pork for making his point. Does raising chickens even have the same impact as raising cattle on the climate?

Yes, I was thinking mostly about beef. Which seems to be the most environmentally impactful meat, by the way. Pork is less impactful and poultry is even less. Obligatory wikipedia link: https://en.wikipedia.org/wiki/Environmental_impact_of_meat_p...

and insect protein is even less than that!

but you'd be hard pressed to find people who would substitute their animal protein with insect protein.

Again, please share the studies to back up your claims. You're either trolling or just very poorly informed and spreading misinformation without checking it. And how do you reconcile the fact that animal agriculture is a large contributor to ecological destruction and greenhouse gas emissions. Here is the result of a 5 year Oxford Uni study that recommends adopting a more plant-based diet to reduce your personal carb…

I'm sorry, here are some articles that supports me when I say that plant-based diet are not good for your health: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1331544/ https://www.ncbi.nlm.nih.gov/m/pubmed/26493452/ https://www.sciencedirect.com/science/article/abs/pii/S00223... https://academic.oup.com/ajcn/article/90/4/943/4597049 https://www.ncbi.nlm.nih.gov/m/pubmed/15072869/ https://www.ncbi.nlm.nih.gov/m/pubmed…

RE: The most part of diseases of this decade are caused by plant based diets Do you have any studies that back up your claim that humans need meat to live a healthy life? Several governmental bodies worldwide state[1] that one can live healthy using a plant based diet and The Physicians Committee for Responsible Medicine[0] even recommend a plant based diet for good health and disease prevention. Did you know B12 is…

btw, please don't do like these guys https://metro.co.uk/2019/11/14/vegan-parents-starved-toddler... feed your babies with meat, we don't have technology (yet) to eat only plants.

Please stop. You've made your point and continuing to push it is just going to cause a flamewar.

> When the beef industry's lobbyist in Washington first tried one, he called his people and said, "Guys, we have a problem". Source? This just sounds like a story made up for advertisement.

"If farmers and ranchers think we can mock and dismiss these products as a passing fad, we’re kidding ourselves. This is not just another disgusting tofu burger that only a dedicated hippie could convince himself to eat. It’s 95 percent of the way there, and the recipe is likely to only get better. Farmers and ranchers need to take notice and get ready to compete. I’ve tasted it with my own mouth, and this fake meat…

To be fair, this could also be to generate some fear in the industry for funding work by the lobbyist groups.

Maybe there will be a need for massive computing in remote areas: Antartica, or space. They need a lot of local storage and compute. And they have low bandwidth.

> YouTube is basically what "SecondLife" was supposed to be. People are exchanging all kinds of valuable information and entertainment on YouTube. A keen observation!

Yeah it's probably because I've been watching a lot of YouTube lately, but it feels like there's just a lot more real interaction going on there than on other platforms. It sounds like Twitch is the same way.

One example: I learned how to clean my toilet from this video.

https://www.youtube.com/watch?v=Wd6pV5lyvG8&t=1s

The comments are hilarious... Tons of people having the same "AHA" moment. (Basically you paper mache your toilet with vinegar and wait a couple hours. Old mineral stains come off like butter!)

Compare a google search for "clean toilet" and it feels like a bunch of SEO-infested crap.

YouTube is more like the "old web" where you can get a real opinion on something.

-----

I have friends who cook and that's a whole other subculture of YouTube. I've been watching a good MMA show. And there are programming streams, and pretty much every programming conference has an archive, which is a rich archive of free information (e.g. PyCon, CppCon, etc.)

I don't know what's going on in Second Life now but to me it feels like it's probably not "real life". I guess people want "life" and not "second life", and video is becoming an increasingly large aspect of the former.

Rebutting my own comment: even if you need heavy computation and storage locally, that still doesn't motivate a decentralized network.

I would think of it as control plane vs. data plane. The data plane can be massively distributed in space, but the control plane can still be centralized.

And of course that's how Tesla works, and how software-defined networking works.

The "powers that be" just need to control software updates and the network's control plane (routing). They can remotely manage distributed resources.

So yeah unfortunately I'm not seeing a big motivator for decentralized networks (which can be very, very slow). You would have to have some need for a lot of local video processing but also a whole way to distribute code and software updates.

And right now that's more centralized than it's ever been. I'm not a fan of the "silent, frequent, and huge updates and pop up new TOS" model but that's the status quo.

> Each point alone requires a long rebuttal that no one would read I'd like to sell you a solution for that. Brief bullet points like the one you made are readable, but when people disagree you need hypertext links to your supporting arguments. I made a web app for creating such trees of arguments. Here's an example in which you'll see I think the dangers of nuclear waste are debatable: https://en.howtruthful.com/o/n…

Cool idea, but I don't completely understand the interface. It's not clear what the 1-5 buttons up top are: does clicking on it record my rating of the claim? What are the numbers next to each of the links in Pros and Cons? They look like they correspond to the ratings above, but I didn't understand how those were derived.

You're on a link that's my opinion, so the numbers next to each link are my ratings. Clicking the buttons on top saves your rating to local storage, and makes a 'You' link to your opinion, where you can put pro/con arguments with your own ratings.

Putting your ratings on the site requires a paid account. I'm making this in my spare time and would have a hard time controlling spam if such accounts are free. I still think the free version is useful for exploring your own opinions.

The rationale is taxation. As more cars go electric they have to replace the gasoline tax.

I would think it should be the other way around where gas cars would need to pay carbon tax. Or we can just call it even. Or in a hopeful scenario, stop oil and gas subsidies.

In a lot of countries the gas tax makes up 5% or more of the total tax income.

Check the rate of nuclear power plants being built. It's fallen off a cliff. The people who finance nuclear reactors already think that nuclear power will be uneconomic in the lifetime of any new plants.

I looked that up. There are 450 plants in operation worldwide and 50 under construction. That sounds like healthy growth. https://www.world-nuclear.org/information-library/current-an...

We will need at least 3x of that amount (assuming 70% renewables). Even if you can somehow build 50 nuclear plants per year it will still take 21 years to build the next 1050.
