I would sooner argue for eating insects vs. lab-grown protein made by a corporation. I have no trust for corporations to produce safe and emergent solutions to the problems we face as a species and world. They have no incentive to do the right thing and put the brakes on when things are looking bad.
Just trying to ground things into our current reality. But yeah, I think in a world where there is an incentive to do good, it’s a no-brainer that we could do stuff like this in a lab and in a much more efficient way than agriculture or raising livestock/etc. for protein sources.
