[Harry Potter] Is the modern muggle world "ready" to know about magic?

If not, at what point would it either be okay, or impossible to hide?

In terms of being able to handle the knowledge that magic exists, they were ready centuries ago. From the wizard perspective, they'll never be there.

The secrecy of the magic community was artificially created and maintained for the benefit of the magical community. Prior to that, there were non-magical folk who knew the score, or at least enough of the score to be a hazard if they got their shit together. Arguably, this has gotten both better (a single mindfucked leader can tell millions of muggles a protective lie instead of mere dozens or hundreds) and worse (machine guns, nerve gas, muggles mashing "send" on a cell phone video before they get obliviated, and so on), but the core situation hasn't changed. 

If allowed to continue unchecked, muggle tech will eventually reach the point where the footprint of the magical community becomes impossible to conceal. Wizards will need to make a choice. Either they let this happen and step into a world where there isn't an iron wall of secrecy protecting them, or they go out of their way to terminate muggle science advancements that can pull back the veil.
