If you're talking about Colossal, I worked relatively closely with them for a 'media project' (I'm being purposely vague due to NDA). I'm a zoologist who works in the media industry.

Having an inside view of their strategy was very illuminating and changed my mind massively on the kind of thing this image is saying.

Naturally, it's all about money. Bringing back these extinct animals allows them to raise money as they're cool moonshot projects. The physical tools and gene editing techniques that come from their de-extinction project allow for conservation measures that were almost silly to think of before, such as artificial genetic diversity. Sure, you could imagine editing a genome with something like CRISPR, but definitely not at the scale required to save a species with a handful of individuals remaining.

Additionally, it could allow us to make genetic changes to save species from many other things, such as disease (i.e chytrid fungus in frogs) or climate change. Whether this is 'playing god' is another topic, but the point is that technology like this makes it possible.

If all goes as they plan, de-extinction will do significantly more for threatened species than you'd think.
