Obviously a very very gross generalization (might get called out on it too :P) - But I think the low hanging fruit for modern software is optimizing data layouts for fast processing.
Optimizing code requires a lot of work, and requires skills that people usually learn from experience - therefore a rare and expensive skillset. Data-Oriented Design can be taught, and requires (IMO of course) a far less technical skillset.
