But what made the likes of Newton/Einstein/Beethoven etc. stand out is how much they achieved given the limitations of the times they lived in. The reason I picked those three is all of them were known for being able to devote huge amounts of dedicated time to their specialty (Newton especially, who from memory developed most of the ideas in Principia while under effective lockdown during a smallpox outbreak. But unlike those of us under lockdown in recent years, there were no electronic gadgets distracting him either.)
