I think they're aware of all these problems because they do mention almost everything you said in the linked post thinking through the idea: https://www.elidourado.com/p/cargo-airships Obviously that was simply a post thinking through everything hypothetically and I didn't read anything that seemed like they actually had the best solution, but at least they seem to be aware of the challenges to landing and off-loading cargo efficiently.

This is not a widespread opinion or pattern as I see it. This is first time I am hearing from someone that we in America "build things fast". I suggest reading Eli Dourado's blog: https://www.elidourado.com/ and his many blog posts on HN: https://hn.algolia.com/?dateRange=all&page=0&prefix=true&q…

Yes, the noise level is measured on the ground directly below the flight path of the plane. Interestingly, it’s not just the volume but also the pattern of the boom that can be altered by changing the design of the plane. There’s a great discussion of this here: https://www.elidourado.com/p/50-years-supersonic-ban (Scroll down to the images of the sound wave)

The reef, as currently constituted, is a lost cause, assuming neither political nor technological solutions to global warming emerge. Genetically engineered coral or algae is one possibility[1][2]. Another is carbon sequestration by massive production of olivine sand weathering in the ocean[3]. The cost of reversing anthropogenic climate change since the 1750s are about $16 trillion, which if done over 10 years, would cost 1.7% of global GDP.

came across a related article recently that explored the economics and physics of airships [1]. seems like a monumental undertaking to actually bring to market but the principles seem sound [1] https://www.elidourado.com/p/cargo-airships

Still awesome, I've thought about this actually, especially for transporting high value goods inland from difficult environments to ports (I'm thinking deep in the DRC or in West Africa during the rainy season when the roads are basically unusable) but hadn't considered the overall replacement of cargo ships with them. I thought this was a fun article: https://www.elidourado.com/p/cargo-airships

> We should absolutely work to reduce, reuse, and recycle, No, we shouldn't. We should primarily work on scaling up our energy production. I was long in favour of nuclear, although apparently there's some exciting development in deep geothermal as well. (inspired by https://elidourado.com/blog/geothermal/ ) We shouldn't even try recycling the plastic, but simply burry it. Oil from the ground, plastic back into the ground. With enough energy and a viable waste management process in place, we don't need to bother with reducing, reusing or recycling, but can simply enjoy our lives to the fullest.

Would $99 + gratitude be enough to motivate you to take that time? I got serious value out of this compendium [0] and have been looking for more. Contact info is in my profile if interested. [0] https://elidourado.com/blog/notes-on-technology-2020s/

I have signed up; Eli Dourado says that Project Vesta is a better deal: https://elidourado.com/blog/dawn-of-geoengineering/, but I'm not sure what Vesta is doing or how pragmatic it is to put olivine on enough beaches to matter.

It is suspected (and I think reasonably so) that Bitcoin volatility will decrease over time[1]. Regardless, I think with the financial tools we have developed in the past few hundred years we are very well equipped to deal with volatile assets. Perhaps it is you who doesn't want to think longer about Bitcoin than the two seconds it takes to realize that loaning Bitcoins might be a difficult problem. 1] http://elidourado.com/blog/bitcoin-volatility/

"Stop Saying Bitcoin Transactions Aren't Reversible" http://elidourado.com/blog/bitcoin-arbitration/ Other commenters here have mentioned n-of-m multisignature transactions. This article describes how multisig works, and how it can be used to implement better arbitration than what's been possible with traditional payment systems. Unfortunately we're in the early days of Bitcoin here: support for multisig isn't common, and neither is the awareness of just how important it is for large transactions. We'll get there though.

What are you basing your assertion that most fortune 500 would be in the red on ? Corporate profit (post tax) are at a record high (e.g. http://elidourado.com/blog/the-short-run-is-short/).

I found Eli Dourado's take on 'Race Against The Machine' quite an interesting analysis and somewhat related to this article http://elidourado.com/blog/technologies-of-control-and-resistance/ It's mainly how points of control incentivize some of these factors to move faster, or out of step with the other factors.

Thereputic Plasma Exchange (ie. exchanging blood plasma with saline and albumin) seems a very promising treatment for aging. [1] [2] "These findings are exciting not only because they represent a scientific advance in understanding aging, but also because they herald the first real anti-aging product that could come to market. Therapeutic plasma exchange is FDA-approved (not for aging, but for a bunch of other conditions). I imagine there remain prohibitions on advertising that it can add years to your life, but it is safe, and a doctor can prescribe it off label. It’s also cheap. An automated plasmapheresis machine—which lets you do treatment after treatment—can be bought online for under $3,000. That is less than the cost of a single transfusion of young blood sold by the startup Ambrosia. How long until someone opens a clinic offering plasma dilution? I bet someone tries it in 2021. If it works, people will get over the weirdness, and it could be commonplace by 2030."

While you provide some solid arguments, I feel that you are overlooking certain key elements. I myself feel that the likelihood of Argentina switching to BTC after its upcoming financial collapse is quite low. However I feel that certain niche sectors of the economy could well jump to using BTC. The points that you overlook are: [1] The USD is currently being deflated like never before and could potentially collapse without warning. Thus making it increasingly unattractive to hold over long periods. [2] Argentina's online economy has recently suffered a huge blow with taxes for online purchases outside of the country. BTC is already becoming the international 'money of the internet'. [3] Most importantly, Bitcoin volatility has been decreasing over time as the price & adoption increases. This is something that shouldn't be overlooked as it has huge implications for the pricing of goods and services in BTC. [4] Finally, there are many ways to do fast transactions in BTC. Have you ever tried sending BTC from one android wallet to another? It comes through instantly. Granted that larger BTC transfers would still require more confirmations though. Off-blockchain transaction services could also kickoff soon.
