“Our strategy is to combine AI and Algorithms to rewrite Microsoft’s largest codebases,” he added. “Our North Star is ‘1 engineer, 1 month, 1 million lines of code.’”

That’s insane. Even a good engineer will frequently need years to fully understand one million lines of code - even if the code is organized very, very well.

To compare, one million lines of program code might have around 200000 important symbols whose meaning and complex connections one has to learn and memorize. That’s far more than the average vocabulary one will learn in five years when learning a foreign language to a high skill level. Doing it in a month would be like learning to read and write fine Japanese or Arab literature in a month when you have never spoken a word in that language before.
