The thing is, what if there's an even better horse out there? Once you get on the cloning bandwagon, don't you also lock yourself out of looking/evolving an even better horse?
For a brief moment I thought this would be about something like robotic polo ponies, and considered the idea that four-legged high agility, high endurance robots had advanced significantly without me noticing.
Humans riding racing robots id watch, but not horse racing.
Imagine 10,000 Albert Einsteins and John von Neumanns working together with modern AI on medical, scientific, and societal issues.
Though there could be an Evil Einstein due to upbringing or something.

The stories make me wonder if Argentina is a cloning hotspot, though I may be reading too much into two stories.
