I think this gets at the heart of one of key mindset shifts that we need to make in order to solve climate change at scale.

(thread) Tech and western economies in general (I consider tech to be the leading western economic sector; thus emblematic of its thinking) have all but shed its manufacturing base, choosing instead to specialize in high-margin value-added services and asset-light businesses.

We have delivered and installed three off-grid seed banks to Eden Reforestation Projects, with more to come! Very happy to be able to help accelerate their work!

terraformation.com/blog/eden-refo… If we were a normal business, I'd even brag that we are the exclusive seed banking supplier to the world's largest forest restoration (by trees/acres) organization, but we're the only one who makes these, and I would be overjoyed to have a hundred competitors.

Contrarian opinion: the recession we're having now (or heading into) is caused primarily by covid, and not by monetary policy or inflation or anything like that. To be clear, excess liquidity injected into the system has had distortive effects, but my assertion here is that the prevailing macroeconomic force that is responsible for our current downturn is covid.

Can anyone share a DALL-E example where all six pictures have different composition?

By this I mean usually the six pictures all have the same format e.g. “person/thing in setting” where the variances are just in the person, thing, and setting. But occasionally you will get a set where most of the images will be one composition, while one of them a totally different composition.

(I use “composition” here in the photography sense)

There’s this hand-wringing over how the Fed needs to raise interest rates to stop inflation but if they do it might cause a recession as though the problem is monetary policy when the reality is just that the economy is injured because millions of people are sick/dead. If I said “I’m going to kill a million Americans and then infect tens of millions more with a disease that causes neurological impairment and organ damage,” would you think it wouldn’t cause problems in the economy?

Refuse to be gaslit into thinking that we couldn’t have crushed covid within months. It was a matter of institutional (in)competence and lack of political will.

The incompetent are incompetent precisely because (among other things) they believe certain things “can’t be done.” Everything that happened after April 2020 was perfectly predictable on the basis of well-established epidemiology - every bleating instance of “no one could have predicted X” is completely false and indicates only - again - incompetence on the part of the speaker.

This book was written in 2006 but remains vitally relevant today: a woman went undercover and lived as a man for 18 months and wrote about her experience. Her observations are eye-opening (for women; most men will be like "duh, you had no idea?").

I realized the other day that even at this late point in the pandemic there is a basic thing many people still don't understand about diseases in general that underpins a lot of how we react to epidemics. It is a simple idea, but most people don't realize it on their own. I am a pretty clever guy myself, and while it's obvious once you're told, very few people reason this out on first principles alone, including me. It's this:

Apparently Russia’s COVID death rate is high in large part due to their vaccine disinformation campaign (originally targeted to the West) that backfired once their own people started believing it.

foreignpolicy.com/2022/01/03/rus… “The Kremlin’s initial dismissal of COVID-19 and efforts to spread vaccine disinformation across the West appear to have backfired on its own population, resulting in a vaccination rate that ranks as one of the lowest in the developed world…

There’s likely to be a lot of carbon credit speculation in the coming years. This is kind of good because expectation of rising prices drives demand, which funnels money to actual carbon removal projects.

(1/n) Yet, it seems a little weird if speculators who pick up relatively cheap carbon credits profit greatly in the future just for getting in early. After all, it’s funding more actual carbon removal that’s important, right?

Here's a stat that's a bit politically inconvenient for almost everyone:

Since 2020, there have been more children killed by COVID (~1,125) than in all school shootings since Columbine (169), over 20 years ago. Are you worried about the danger your kids might be in when you send them to school? They are well over an order of magnitude more likely to die from covid infection than a school shooting.

Yeah, you probably still sent them to school, right?

Whenever there's an article about water shortage (esp in California), there's usually a passing mention of desalination, typically then dismissed as being too energy-intensive/expensive.

Something about this bugs me, and I've figured out what it is: 🧵

newyorker.com/news/dispatch/… Yes, water from desalination is (today) typically more expensive than water from a natural runoff (mountain, snowpack, etc) sources.

And the implication is, "Well then, why would we use desalination, a more expensive source of water instead of runoff sources?"

It is generally accepted among online community management experts that permanent bans are in fact a bad idea. This is because online platforms allow for easy re-creation of accounts (over and over), so permanently banning a recalcitrant user typically results in them trying to circumvent the ban by just creating another account.

The NYT reporter (and friends) have taken to claiming that I have misrepresented them:

Of course, that's up to interpretation, because I specifically did not outline or speculate what their motives were.

Two weeks ago, the NY Times asked to interview me regarding Elon and free speech, saying (among other things) that she believed that thus far, no one has been able to succinctly and convincingly offer a strong counter point to Elon's position for society to consider. I was pretty busy at the time and so couldn't do a zoom interview and agreed to do it over email, but that I would first send her my argument against Elon's owning Twitter, and if it was something the NYT was willing to publish unedited, then I could do the interview.

Okay, now I'm being asked "What should Elon do to fix Twitter?"

It looks like the takeover succeeded (easiest hostile takeover ever! I suspect the board secretly wanted to work with Elon, because WELL IT'S ELON). I don't know what it means to "fix" Twitter, but here are a few more detailed perspectives which may shed light on more effective solutions (rather than solutions which backfire).

This part of my recent tweetstorm is one of the most misunderstood, so I would like to clarify it.

My usage of "by scientists" was taken to mean that acceptable discourse should only happen if the participants are (qualified/experts/etc), but that's not what I was after at all. A better way of putting this is "if it were being discussed in a calm, polite manner on Twitter."

It's the behavior that matters, not the content or the participants.

I've now been asked multiple times for my take on Elon's offer for Twitter.

So fine, this is what I think about that. I will assume the takeover succeeds, and he takes Twitter private. (I have little knowledge/insight into how actual takeover battles work or play out)

(long 🧵) I think if Elon takes over Twitter, he is in for a world of pain. He has no idea.

These victories are kind of hollow now that my wife is consistently solving the Semantle almost every day. She has figured out a way to extract information from the cold guesses to form multiple vectors in the 300-dimensional space so that she can hone in on the answer far more quickly.
