> The AI built-out is by far the fastest growing energy consumer in the world, and they’re being built with fossil fuels, or drawing green energy demand away from replacing the fossil fuels depended on by other industries.

This paragraph links to the IEA report which does indeed call datacenters the fastest growing energy consumer, but also says:

> Despite rapid growth, data centres remain a relatively small part of the overall power system, rising from about 1% of global electricity generation today to 3% in 2030, accounting for less than 1% of total global CO2 emissions.

For scale, beef production is about 9% of total greenhouse gas emission.

> It seems like either one evaluates the contents of the `box`, and would only make a difference if you tried to use `x` afterwards?

More or less. x^ moves the whole box whereas x* copies the contents of the box.

> Awkwardly, it also hasn't been assigned so I'm not sure the box is accessible anymore?

Yes, if you move something and don't assign it then it gets dropped, same as rust.

> The goal is that most of your code can have the assurances of static typing, but you can still opt in to dynamically-typed glue code to handle repls, live code reloading, runtime code generation, malleable software etc.

My bad :)

EDIT I totally missed the context

I've tried using binaryen, and I've also tried emitting raw wasm by hand, and the latter was far easier. It only took ~200 lines of wasm-specific code.

One of the dynamics is that people get older so they move into different buckets.

We can make the model way simpler to make it clearer. Say in 2020 we hired 1000 20-24yo, 1000 25-29yo etc and then we didn't hire anyone since then. That was five years ago, so now we have 0 20-24yo, 1000 25-29yo, 1000 30-34yo etc and 1000 retirees who don't show up in the graph.

Each individual year we hired the exact same number of people in each age bracket, and yet we still end up with fewer young people total whenever hiring goes down, because all the people that got hired during the big hiring spike are now older.
