All our genetic engineering tweaks existing organisms. We cannot make life in the lab.

Except for the lab-built bacterial chromosomes (1), the lab-built entire viral units (2), and the lab-built xenobases (3).

Edit: just to add, I wouldn’t accept “we have not done it from scratch yet” as a valid argument that we cannot do better than natural selection, any more than I would accept ”$person has not yet fabricated a CPU” as an argument that $person can’t code better than at least one professional CPU designer.

CPUs weren't evolved.
Irrelevant. I thought that would’ve been clear from me using the comparison as an example of a bad argument.

Also, not even correct, assuming I have been correctly informed that simulated evolution is used for some optimisations of e.g. precise physical transistor placement.
