I don't think so; maybe 100 years. To achieve 1,000x magnification with an optical microscope, you need oil (or some other fluid with a refractive index similar to that of the lens) between the objective lens and the subject.

I believe the maximum theoretical magnification you can achieve with an optical microscope is about 1,400x. The limit is imposed by the minimum wavelength of visible light.
