Eventually, you are going to hit a wall. Humans are only capable of running so fast before you can’t improve on time anymore. You can climb only so hard before the holds are so small it would be impossible for anyone to pull on. You can only power lift so much before your bones would break.
The giant leap in physical achievement is over. In the last 50 years or so, every major record has been broken thanks to technology, diet, and training. So, where do we go from here? Because the records being broken today are often measured by tenths of a second.
Perhaps, this is one of the reasons we are seeing a rise in popularity of E-Sports. Either way, finding ways to make a giant leap forward are more difficult than ever.
The bottom line: Don’t scoff at incremental improvement because that’s likely the path ahead that’s available. Making the next leap is likely going to be assisted with more technology than we ever imagined.
