I think it’s useful to distinguish between ‘economic thinking’ as described by your parent, and the current western economic leaning toward market economies. As I understand the comment, economic thinking is a story about adaptive systems,

That position is appalling to me, but I’m impressed by your intellectual honesty and how you answer the question head on.

What is the goal then, for profit seeking advertising companies like Google and Facebook?

Nobody would enjoy having a diamond without advertising. Maybe a child, to put with her collection of other rocks and shiny things. While I agree with your parent that advertising can help people enjoy things more, I don't agree with t

Do you have evidence that economic migrants are lower IQ than people in more affluent countries?

I wonder if that was poor wording from the reporter. They write “capped” but then describe a liquidation preference.

Any discussion about Taleb always leads to questions about why he picks such public fights. I've said this before: The most salient anecdote Taleb tells about himself is the one where he's going onstage to debate an opponent. He a

AvE did two videos on the collapse, both very good. The comments are excellent, and worth skimming even if you’re generally allergic to YouTube comments. There are explanations from several ironworkers who actually erect and dismantle crane

The inability to keep assets hidden ("safe") means an LLC would be more valuable for a non-wealthy person. While a wealthy person squirrels away their assets somewhere, a poorer person needs LLC protection exactly so their perso

These are all benefits for John Deere. I don't think anybody thinks there is no incentive for JD to do this. Reduced manufacturing expense - Yup, DRM and platform lock-down (machinery is a platform??) increases profits. Tractors sure a

Prefacing a criticism with "XXX is an upstanding person, but..." is just shorthand for saying "I am aware of and actively trying to avoid ad-hominem arguments, and genuinely believe my concerns are with the institution/s

I think it was meant as an analogy.

Your instincts are excellent: using heat directly is always and everywhere better than turning it into a fungible commodity like electricity, only to convert that electrical energy to some other form later. (Creating liquid fuel is no diffe

Something like 55-60% of the thermal energy created by burning fossil fuels is currently wasted.

Thanks. If the scale is lacking, I get it. But to be clear, I’m talking about a series of 10MW electrical power plants each with 95% capacity factor. Using your number downthread of 60kW/gallon, that translates to about 1.4 million gal

Hi Rob. I'm CTO of a company that generates electricity from waste heat at industrial facilities. Pipeline compressor stations often generate 35MWth+ in waste heat, which we can use at about 20% efficiency to generate electricity. Many

I really liked this essay, and I think I would really like its author if I knew her. At the end of the essay, the vague sadness I felt was joined by a pretty unsympathetic “well, what did you expect?” kind of feeling. I didn’t like that, it

At least in Toronto and Edmonton, the two places I have been involved with commercial real estate, I have never heard of a landlord footing the bill to outfit a space.

As I understood the article, in one part of the experiment they set up alternate regions of heat and cold within a sample of graphite using interference patterns from two laser sources. When they turned off the lasers, instead of the hot re

Although it’s controversial, I don’t think there have been tsunamis of ridicule from every direction hitting people saying fracking increases the odds of an earthquake, which is what this is about.

Not denying we have a broken system, but how could we outlaw real estate investment without removing the option of renting an apartment or house?

Your anecdote created a very strange comment string with a lot of comments from people who seem to be strongly defending libertarianism, except for the part about honoring contracts.

Is your question rhetorical? In case it's not: 1) Web applications make it easy to require monthly subscriptions, which many people don't like but is great for companies 2) Web applications can be more easily monetized through ads

The most exciting company here to me is Prometheus, who is mentioned in several threads here. It bugs me though, that the TC blurb, and the comments here, and the Prometheus website, all say the company is turning CO2 into gasoline. That st

Had a look through the patents. Their IP seems to be around a forward-osmosis separation process. They use CO2 in ammonia on the dilute side of the osmosis process. So my complete seat-of-the-pants, duffer-on-the-bench guess is that they ha

I’m not sure 20-somethings are more civic minded. They voted in the last election at participation rates consistent with the last 40 years for that age group. Participation rates will probably increase as they age. Unfortunately priorities
