That's like saying you aren't building a house if you use a hammer to drive nails instead of your hand. AI is just a tool like any other, and you use it to build things like you would any other tool.
One could even argue what defines AI instructability is heuristics as opposed to specifics
A coding agent is more like a carpenter, a mason, an electrician,... rather than a hammer in that case.
And you won't get purity tests from the layperson: in the end, you're responsible for the build quality so if you tirelessly labor/oversee those teams you're considered capable; if it ends sub-par, then you're a stooge.
Really? Last time I checked, other tools can operate without ripping off the works of millions of humans.
