Runner who has done a marathon here, I think the wall your hitting is when your body is switching gears from warm-up to cardio. Everyone is suggesting the couch-to-5/10k programs and that may help. I would suggest pushing your time spent running a bit further, more time doing cardio should improve things.
I just restarted my long-run training for the year (because its not cold outside anymore, and I want to run a race this year, its been a bit) and just passed that point where I can just go without having to take walking breaks on my "default loop".
Also goals, having something to look forward to or to work towards helps a lot. Keep up the good work.
There is still a pretty solid divide between us and our technology (for now). We still type on keyboards with our hands and make prosthetics. It gets blury when discussing things through a medium where technology is the means of communication. I could be an AI, you could be a robot, we "humans" already cant really tell the difference most of the time. I think your prediction would hold true when the integration between meat and machine starts being physically indistinguishable.
