I don't think any 'interesting thought' that serves as a conclusion to an article should begin like so: | 'With radiologists, I’m totally speculating and I have no idea what the actual workflow of a radiologist involves...' Speculation from a place of ignorance is suitable for bar-side musings, not an article that wants us to take it seriously.

That's part of a quotation, as clearly stated in the article.

``` Each of these phenomena have a name: there’s Jevons Paradox, which means, “We’ll spend more on what gets more productive”, and there’s the Baumol Effect, which means, “We’ll spend more on what doesn’t get more productive.” ``` I don't think that's exactly right. Jevons says "we consume more on what gets more productive" and Baumol says "the unit cost increases for that which is less productive". The typical examp…

The modern day example that really made Baumol click for me is child care, particularly day care. It’s a highly labor intensive with basically minimal opportunities for productivity enhancements (due both to regulation and parental preferences, as well as just baseline sheer human decency). As the rest of the economy becomes more productive, the relative cost of child care goes up and up and up - which is why we now see situations where two-earner households can an entire after-tax income consumed by child care costs once they need to put 2-3 kids into daycare.

you accidentally knock a hole in your wall, it’s probably cheaper to buy a flatscreen TV and stick it in front of the hole What I recently did is that I 3D-printed an object with PLA that exactly fit the whole and just glued that in with assembly glue. What does the HN panel say? Is it a solution? Or does it have any downside?

It's fine.

The biggest actual problem would be in a fire, the PLA will burn and let the fire into the wall cavity, where drywall would maintain a barrier for much longer - that is why we have drywall in the first place, it is a decent fire barrier.

> If you can make $30 an hour as a digital freelance marketer (a job that did not exist a generation ago), then you won’t accept less than that from working in food service. And if you can make $150 an hour installing HVAC for data centers, you’re not going to accept less from doing home AC service. Plenty of people work jobs for less money because they enjoy the work more. I’m not sure if it’s worth reading what fol…

That might be true but that doesn't mean the effect is false in the aggregate. The classic example given in Baumol's paper was a violinist[1]. Sure, playing a violin might be more enjoyable than working in HVAC or churning out enterprise CRUD apps, and some people might even accept a paycut[2] to be a violinist, but that doesn't mean the effect isn't real. Despite zero productivity growth in being a concert violinist…

I'm still amazed at how Baumol got his name on something already named [1].

Two signs this article is coming from too-privileged a point of view for its observations to be meaningful or useful to 99% of the population.

Earlier quoted context omitted.

Also as noted in the prior dupe, the article also misunderstands it's own topic, as explained in ( https://en.wikipedia.org/wiki/Jevons_paradox ): In economics, the Jevons paradox occurs when technological advancements make a resource more efficient * to use* ; however, as the cost of * using the resource drops* , if demand is highly price elastic [PED] , this results in overall demand [for the resource] increasing.…

>The cost to use tokens is already zero or deeply negative, depending on your accounting ??? Sure, there's zero cost tokens in the form free chatgpt, but negative cost implies that you're getting paid to consume tokens, which I'm not aware of?

I mean, sure, sign me up, and I'll use a bunch of negative-cost tokens...

What productivity improvements would be possible if not for regulation?

I would simply do the normal thing of covering the hole with drywall patch screen, covering that over with drywall joint compound, letting it dry, sanding, and painting. This is an under $50 trip to Lowes, and certainly cheaper than a flatscreen TV.

The blue-line/red-line diverging price graph is such a great litmus test for someone's ability to do even a single round of interrogation.

Here's the question to ask:

Which of these have economies of scale, are scale-neutral, or have diseconomies of scale?

Ta-da!

Three sectors that have diseconomies of scale: education, healthcare, housing.

Essential services aggregate in the red because non-essential services that have diseconomies of scale... wait for it... never achieve scale! Then you have government step in because the services are important (often with hard-to-capture upside, ergo limited incentive for private investment to begin with), and now you have an aggregation of essential, expensive, government-involved services.

The solution I was taught as a child is to saw the hole square, put a section of 2×4 behind it spanning the hole, held in place with a drywall screw through the drywall on each side of the hole, cut a square chunk of drywall small enough to fit in the hole, put a drywall screw through the middle of it into the 2×4, and tape, mud, sand, and paint.

I suspect that this procedure is faster and easier than taking a 3-D scan of the hole, 3-D printing a PLA patch, and gluing it in, but it does require most of an hour and the appropriate materials on hand.
