Flynn doesn’t think the effect is a “real” gain in intelligence or g, just using “scientific lenses” and greater abstraction. There are some who point to other physical changes that have occurred and better nutrition though.
Yet… if you look at what really matters: How good are people at doing science? How skilled is their computer programming? How wise is their economics? That’s all phenotype, not genotype. It could well be 100% environmental and not at all related to the hereditary g; so what? It’s actual smartness, actually improving, making the world actually better.
