Since we have CRISPR and all the other cool stuff with gene splicing, might we be able to give ourselves gills one day?

It just seems like it would be a really cool thing to have gills and be able to populate the oceans in the same way we populate the land. We could have houses and shops and vehicles, andgo on walks/swims and just kind of live underwater.
Start a whole new second species of human here on earth maybe, Who knows?
There's not enough oxygen in water to support our metabolisms, even if we had gills.
Fish are adapted to conserve and use less oxygen, from slower metabolic rates to more options for anaerobic respiration that doesn't poison oneself from within.
Well thats not really the most relevant thing here even if correct because you could give someone gills and let them keep their lungs too just having the gills to extend how long we can dive would be useful
