No. Just no.
Your affirmation of modern supremacy is incorrect. Your disdain for the ancients is inaccurate. Your general point is just plain ignorant.
The true zenith of truly amazing detail painting isn't even close to the current day. Any art historian would laugh before arguing for either the Dutch school in the late sixteenth/seventeenth century, or the general proliferation of amazing painting in the late nineteenth. The current day has too many more effective and efficient methods of image creation, so painting is de-incentivized.
As for the ancients? Well assuming you mean actual ancients and not just "folks from a long time ago," lets take anybody from later periods; Rembrandt, Constable, even your straw 16 year old. Take them, and force them to paint on papyrus, or stucco walls, or calfskin. Force them to use paints and brushes that could only generously be described as primitive. Brushes that a modern housepainter would call "imprecise." And finally, lets remove any knowledge they could only have gained by studying other painters who invented new methods only far after the ancient period.
I reiterate. No.
