Thanks for editing to cite your sources. They seem to show a slight increase in energy usage since 2010. You must be using 2020 pandemic data as your comparison which is very misleading. But 2018 is the same as 2007, so I think it is fair t

Where are you getting your data from? I see here [1] that energy usage is static now (but not since 2000), but it is not declining. But that means it is declining per capita. But again, I would like to see manufacturing outsourcing taken in

If we presume that the entire US became gradually powered by nuclear (along with solar, wind, and hydro), we probably wouldn't have ever seen an actual global decline in fossil fuel usage at any point other than perhaps coal by a littl

I agree that Europe is having real success. But we need to also keep in mind where energy is being used the most now and in the future. In the long-term Europe going 100% renewable by itself doesn't change the global energy picture muc

This is actually how Bitcoin is supposed to work if successful. Normal banks perform final settlement with Fedwire. That is actually what Bitcoin is competing against (except at an international scale). It is confusing because stores keep w

That's not a counterpoint, it is a case in point! There are some energy sources like whale oil that had supply issues and roughly a single use that got displaced. But for our major energy sources with a vast supply we keep finding ways

Actually I suspect we need both approaches. But I agree we need to both support economic needs and make it not feel like extra work to use less energy (although there may be some extra up front costs).

I agree with your statement. However, we need to keep in mind that displacing an energy supply in one country keeps the resource available and the price lower so that another country may use more of it. We may have real success with reducin

But the energy usage increased dramatically. So it is possible that the usage of wind power and water power never declined much (it would be interesting to see data for this). A clearer case might be something like using animal power (for p

Whales were going to go extinct so I don’t think there was much choice. Also it had just one main use at the time for oil lamps. That can certainly be disrupted. But if it was a plentiful source it may have been possible to figure out how t

This is a straw man argument. If Bitcoin is useful, it is for final settlement for larger institutions. Of course a proper rollup that works at scale is missing.

I want to point out that overtaking oil doesn't mean displacing it. History described in this chart predicts that the best we can hope for is that oil usage will very slowly decline like biomass or coal. I point this out not because I

Solar already hit a supply shock this year that has increased the cost of installation (it has been reliably going down before this). Solar growth is expected to be closer to just linear this year. I hope this is temporary due to all the su

It seems they found a way to make the blockchain even more carbon intensive by burning up rocket fuel as well.

This graph is a great reality check: https://ourworldindata.org/grapher/global-primary-energy Humanity has never displaced an existing energy source with a new one. Instead total energy usage grows. Our only success wi

What’s missing in this article is a proper discussion of the level of government for each child. This ends up being the limiting factor for most who are not wealthy.

Rents have been depressed due to eviction moratoriums So I don’t think this metric is useful right now to gauge the housing bubble. The main mistake usually made with housing is not accounting for inflation. Here is a data driven analysis t

There is a new XIV-like ETF just launched called SVOL. It reduces the exposure level and hedges risk with options (XIV ended up collapsing!). https://www.simplify.us/blog/volatility-premium-harvesting-r...

Does there need to be subtle bugs at the interface if Rust exposes the interface as a C ABI? I think the idea of this article is that you don’t need to understand two tool chains but instead can focus on the harder task of understanding two

Lyn Alden actually also has one of the best explanations of the price of gold! [1] It is tightly correlated to the broad money supply modified by changes in real rates (10 year - inflation). In August we saw the 10 year rate start rise and

Not quite. Berkshire owns non-public companies. You can skip ETF management fees and just look up their latest SEC filing. Here is a pie I made in M1 (which you can invest with the click of a button if you have an account) which is similar

I agree that returns would not be much different if they had avoided bad M&A. They have tons of cash and have to do something with it if they don't give it back to shareholders. Amazon has historically had the least amount of cash

My understanding is that the vast majority of these M&A destroy capital. The reason to own dividend stocks is not because they pay dividends but because they don't have tons of cash lying around to spend on low value projects or M&

There has been a rumor of a stock split late this week that may have been leading to a speculative rise but for whatever reason the stock was already up 3% this week (and 13% this month).
