If Uncertainty Principle is a result of 'fiddling' of an apparatus with what is being observed (for example light particle/wave of a detector fiddling with particles/waves being observed), then wouldn't uncertainty principle cease to apply if in the future a 'smaller' or 'less interfering' element of nature is discovered for use for observation? Say, a via the use of a "string powered detector" or whatnot.
Also, I notice a lot of disagreement between websites on it. The most 'zany' appear to imply the principle is about an abstract concept of "the observer can not know" while others take it down to earth and talk about interference of the apparatus observing and the particles. I tend to think the 2nd camp is the most rational, hence my question: why do they take it so strongly and not consider it a "weak" principle, since, they don't seem to have proven they will "never" be able to measure them without interfering with them [since it appears in the future such a method/technology/science may be discovered], unless I miss something?
Thank you in advance for any help you may offer.
