Really? We need to stop asking these types of questions. The question should not be whether something is primal, it should be whether something is plain and simple, good or bad for our well being.
Going into outer-space, driving cars, internet, these are not "paleo/primal". But that means diddly-squat. It's not about living as we once did 100%. It's about cherry picking the things that actually were good for us and using them to our advantage. You don't need to rip off your clothes, and go live in a jungle somewhere. Unless that's your thing.
