I’d like to see them reconstructing precious animals that have gone extinct. There are quite a lot of those, perhaps a few species might solve the food problem for the ever-growing human population. Yummy stockoceros, for example, and bison antiguus.
And restaurants could fax over burgers you could print on your 3D printer.
There are already food printers.
Just print me out a side of moose. It doesn’t have to be the whole living biting animal.
