Cognition however is what defines our very soul. Being human is intricately linked with it in a way that the physical is not. Stephen Hawkings could be an example of that.
Ceding cognition presents a very real and existential problem for humans. What’s left? We have literally no other defining qualities.
About your examples: people are more obese than ever and cars certainly don’t help. Only the elite few have the resources to focus on something as useless as running fast. “We” as a society cannot run fast(er) and I’ll indeed argue that this ability decreased because of technology. Not that I particularly care about running.
