Is This Like a Classical Wave?
A classical wave also spreads out. The more localized the region in which the wave is confined, the more the wave spreads out in time.
Why isn’t that called an “uncertainty principle” and given philosophical hype?
Because nothing is really “uncertain”: the wave is definitely spread out. If you measure where it is, you get the answer: “It is spread out.”
This is different in quantum mechanics where each particle is not spread out. Only the probability of where the particle will be found is spread out.
