Not really. If you walk at an easy pace of 2 miles per hour, and start at 6am, you'll be done in time for an evening meal. At 3 mph, you might even make afternoon tea.
The world record marathon times are, in fact, only about 4-6x what you can do as a walking human being.
I don't know the answer, TBH. I've been a programmer for nearly 35 years now, and at times along that journey I've been the 10x coder. But I'm not anymore (just like I can't go sub-3h for a marathon at this point), despite knowing a lot more and being better by some metrics than I was during my 10x periods.
"If you're okay with the message getting there in 3 and a half hours instead of 2 hours, do we really need to fetishize 10x performance?"
YAGNI is a way stronger principle to base your success on than finding or training unicorns.
