Indeed, even without transhumanism, a coexistence combines the strengths and weaknesses of both humans and machines. AI works differently from humans; therefore, they do not have the same mental bottlenecks or preconceived notions as we do especially when adequately built to avoid biases.

As AI will develop new ways of thinking they might suggest innovative perspectives that change human thought patterns positively. Often insurmountable in our current state. We can learn greatly from AI technologies by expanding knowledge past where biological senses end.

Coexisting with innovation integrates manpower better than implementing robust cyber modifications which risk opening loopholes in their implementation, so yes: it is indeed feasible and should be targeted instead perhaps?
