    Great write-up. People keep saying "we can just write tests" or more recently "we can use formal verification," thinking these are sufficient safeguards we can use and then relegate all the implementation to LLMs. But the fact is that probabilistic guessing machines can't save them. People can't escape the need to actually understand the things they are building.

      How do managers build software?

      The fact is when LLMs get good enough you WILL be able to build software without reading/understanding the code.

      Whether or not you think we are already at that point is kind of an unimportant detail.

      I would say we are quite close, depending on the type of software you are building.

        Manager's do not build anything despite what the management-class might want you to believe.
