There's a not-very visible but nonetheless real amount of planning and "portfolio management" that goes on behind the scenes into choosing which ostensibly "random pilots" to produce. Yes it's kind of a "reptilian" strategy by design (as opposed to "mammalian", focus-on-one-baby-at-a-time), but there is a lot of careful selection done, even if the results look random. More and more, this is a data/ML-driven space, and less and less reliant on human expertise (with human insights but also human blindspots and biases).
