Gene editing is also the only way we'll get offworld-hardy humans. The time it will take to naturally select, when throwing unfit after unfit is impractical. This is still the same concept as "thousands of [model here] walking around", but with a focus on different traits.

Which is why I roll my eyes realizing that none of that will happen for a very long time but if you could make 60-year-olds look like 30-year-olds with an mRNA treatment or something similar, you would make Bezos and Musk look like paupers. It wouldn't even have to make you young on the inside and you'd still die in a decade or two but at least you'd leave a beautiful corpse because that's all that matters in the end.
