Yikes, what a flippant comment. The mix composition (meta's AI is helping with this) is separate from the wet concrete product. The parent is suggesting a way to test that the mix is properly mixed before pouring, not suggesting a way for construction workers to determine that the chemical properties of the mix will be correct on site. Furthermore, they're not even using LLMs, so it's not "AGI".

Do you actually see construction workers being replaced? We need more stuff built than we have people or time. We have spent a century improving process and tools and if we 10 years from now could build 3 times as much with the same people we would find a use for them all.
