The studies were conducted over different time periods when average nutrition changed, and demographics changed. And the study demographics just vary by location.

Height loss with age is incredibly well documented. Here’s a few more studies.

This is just basic medical textbook information. No one in the world is arguing that this phenomenon doesn’t exist.

If you are the kind of person who thinks AI will drive down the wages of software engineers that much, you have to think that it is at least a 2x multiplier.

$65k salary all in for a company is easily $100k. So spending anything less than $100k would be what you would aim for.

Most small businesses fail because they were never serious businesses to begin with. A business closing down after running for a year with no profit isn’t relevant.

But also short people living longer has so many more possible explanations than less overall fat.

As for 2, men in the US are getting shorter because of immigration which adds many confounders.

That’s not what I was saying.

I was saying that the perception of management is that the tickets are interchangeable. Not that the tickets are actually interchangeable.

Notice what I said after that. That this usually results in seniors coming in at the end to rescue the project.

But it’s wrong to model businesses as if they have no ability to increase profit per customer and predict catastrophe from minor reductions in customer traffic.

They can and do figure out how to do more with less.

In reality most business can do things like cut hours for staff, postpone upgrades or long term maintenance, cut amenities, raise prices etc…

If most businesses were structured in a way that a small decline in customers immediately puts them out of business, any minor economic downturn would be an unrecoverable positive feedback loop for the economy.

I’m not saying a 10% drop won’t put a lot people out of business, but it’s not as much of an existential crisis for the economy as a whole as that story makes it seem.

This is the theory, but I’ve never worked anywhere (and I’ve worked at a lot of places over 20 years) that actually did it like that in practice.

What tends to happen is that the EMs and PMs look at who’s free and give that person the task. This means that sometimes you get a senior leading a simple project and sometimes you get a junior leading/designing a complex project (usually with help from a very minorly technical PM).

Then the senior/staff/principal (often on a different “special” team) gets pulled in at the last minute to rescue the project.

If your company is highly product driven, you’ll often find that the juniors end up leaving projects more often than not because they will tell the PM exactly what they want to hear.

15 devs putting out 400k LOC a year into the same codebase is not normal at all. I’ve never seen anything close to that kind of rate of growth across that number of people.

And 50 engineers is not even remotely close to a small startup. I have worked at a startup that had 50 engineers after a few years, but it was a multi billion dollar unicorn.

>”Have you worked at many startups?”

In response to a question about a legacy codebase at a startup. That implies that they think whatever they are doing is common. And forking a multi million line codebase and heavily developing it isn’t common for startups.

I’ve never seen a startup with a multi million line legacy codebase.
