If I mention Plato's Forms to people they generally react along the lines of "They used to believe weird stuff back then."
But ever since Emmy Noether at least, studying symmetries and invariants has been one of the keys to theoretical physics. I recently read a take-down of the purported EM drive that relied almost entirely on the equations and the symmetries.
The equations are seen as the important thing, the fundamental thing. The individual instances of atoms aren't as important as the Form behind them. Abstractions matter more to us.
That's not obviously either good or bad. Certainly it's bad if it's wrong and the Form is central to your life (an idol).
