You don't say.
Imagine for a moment you had a machine that allows you to throw bricks at a certain distance. This shit is useful, specially if you're a griefer; but even if you aren't, there are some corner cases for that, like transporting construction material at a distance.
And yet whoever sold you the machine calls it a "house auto-builder". He tells you that it can help you to build your house. Mmmh.
Can house construction be partially automated? Certainly. Perhaps even fully. But not through a brick-throwing machine.
Of course trying to use the machine for its advertised purpose will go poorly, even if you only delegate brick placement to it (and still build the foundation, add cement etc. manually). You might economise a bit of time when the machine happens to throw a brick in the right place, but you'll waste a lot of time cleaning broken bricks, or replacing them. But it's still being sold as a house auto-builder.
But the seller is really, really, really invested on this auto-construction babble. Because his investors gave him money to create auto-construction tools. And he keeps babbling on how "soon" we're going to get fully auto house building, and how it's an existential threat to builders and all that babble. So he tweaks the machines to include "simulated building". All it does is to tweak the force and aim of the machine, so it's slightly less worse at throwing bricks.
It still does not solve the main problem: you don't build a house by throwing bricks. You need to place them. But you still have some suckers saying "haha, but it's a building machine lmao, can you prove it doesn't build? lol".
That's all what "reasoning" LLMs are about.
