I think this is a pretty solid analogy but I look at the metaphor this way - people used to get strong naturally because they had to do physical labor. Because we invented things like the forklift we had to invent things like weightlifting to get strong instead. You can still get strong, you just need to be more deliberate about it. It doesn't mean shouldn't also use a forklift, which is its own distinct skill you also need to learn.

It's not a perfect analogy though because in this case it's more like automated driving - you should still learn to drive because the autodriver isn't perfect and you need to be ready to take the wheel, but that means deliberate, separate practice at learning to drive.

> people used to get strong naturally because they had to do physical labor

I think that's a bit of a myth. The Greeks and Romans had weightlifting and boxing gyms, but no forklifts. Many of the most renowned Romans in the original form of the Olympics and in Boxing were Roman Senators with the wealth and free time to lift weights and box and wrestle. One of the things that we know about the famous philosopher Plato was that Plato was essentially a nickname from wrestling (meaning "Broad") as a first career (somewhat like Dwayne "The Rock" Johnson, which adds a fun twist to reading Socratic Dialogs or thinking about relationships as "platonic").

Arguably the "meritocratic ideal" of the Gladiator arena was that even "blue collar" Romans could compete and maybe survive. But even the stories that survive of that, few did.

There may be a lesson in that myth, too, that the people that succeed in some sports often aren't the people doing physical labor because they must do physical labor (for a job), they are the ones intentionally practicing it in the ways to do well in sports.

I can’t attest to the entire past, but my ancestors on both sides were farmers or construction workers. They were fit. Heck, my dad has a beer gut at 65 but still has arm muscles that’ll put me to shame — someone lifting weights once a week. I’ve had to do construction for a summer and everyone there was in good shape.

They don’t go to the gym, they don’t have the energy; the job shapes you. More or less the same for the farmers in the family.

Perhaps this was less so in the industrial era because of poor nutrition (source: Bill Bryson, hopefully well researched). Hunter gatherer cultures that we still study today have tremendous fitness (Daniel Lieberman).

The fact that Greeks and Romans had weightlifting and boxing gyms for their athletes in no way makes it a "bit of a myth" that people used to get strong naturally by doing physical labor. For example, average grip strength of people under age 30 in the US has declined markedly just since 1985.

We may not have any evidence that they had forklifts but we also can't rule out the possibility entirely :)

> I think that's a bit of a myth.

Why do you think that? It's definitely true. You can observe it today if you want to visit a country where peasants are still common.

From Bret Devereaux's recent series on Greek hoplites:

> Now traditionally, the zeugitai were regarded as the ‘hoplite class’ and that is sometimes supposed to be the source of their name

> but what van Wees is working out is that although the zeugitai are supposed to be the core of the citizen polity (the thetes have limited political participation) there simply cannot be that many of them because the minimum farm necessary to produce 200 medimnoi of grain is going to be around 7.5 ha or roughly 18 acres which is – by peasant standards – an enormous farm, well into ‘rich peasant’ territory.

> Of course with such large farms there can’t be all that many zeugitai and indeed there don’t seem to have been. In van Wees’ model, the zeugitai-and-up classes never supply even half of the number of hoplites we see Athens deploy

> Instead, under most conditions the majority of hoplites are thetes, pulled from the wealthiest stratum of that class (van Wees figures these fellows probably have farms in the range of ~3 ha or so, so c. 7.5 acres). Those thetes make up the majority of hoplites on the field but do not enjoy the political privileges of the ‘hoplite class.’

> And pushing against the ‘polis-of-rentier-elites’ model, we often also find Greek sources remarking that these fellows, “wiry and sunburnt” (Plato Republic 556cd, trans. van Wees), make the best soldiers because they’re more physically fit and more inured to hardship – because unlike the wealthy hoplites they actually have to work.

In the original form of the Olympics, a Roman senator would have been ineligible to compete, since the Olympics was open only to Greeks.

Weightlifting and weight training was invented long before forklifts. Even levers were not properly understood back then.

My favorite historic example of typical modern hypertrophy-specific training is the training of Milo of Croton [1]. By legend, his father gifted him with the calf and asked daily "what is your calf, how does it do? bring it here to look at him" which Milo did. As calf's weight grew, so did Milo's strength.

This is application of external resistance (calf) and progressive overload (growing calf) principles at work.

Milo lived before Archimedes.

Dad needs to respect that we need rest days.

[gadflyinyoureye]

I looked up the weight of cows from that era. Only about 400 lbs. Seems doable.

[epiccoleman]

> what is your calf, how does it do?

... it's a calf, dad, just like yesterday

[chairmansteve]

Milo might have had slaves, the forklifts of his time....

> people used to get strong naturally because they had to do physical labor.

People used to get strong because they had to survive. They stopped needing strength to survive, so it became optional.

So what does this mean about intelligence? Do we no longer need it to survive so it's optional? Yes/No informs on how much young and developing minds should be exposed to AI.

You don’t need to be strong to operate a forklift but you definitely need to be able to write the simple code to be a SWE.

[hennell]

>if the goal is to build up your own strength I think you missed this line. If the goal is just to move weights or lift the most - forklift away. If you want to learn to use a forklift, drive on and best of luck. But if you're trying to get stronger the forklift will not help that goal.

Like many educational tests the outcome is not the point - doing the work to get there is. If you're asked to code fizz buzz it's not because the teacher needs you to solve fizz buzz for them, it's because you will learn things while you make it. Ai, copying stack overflow, using someone's code from last year, it all solves the problem while missing the purpose of the exercise. You're not learning - and presumably that is your goal.
