Even if someone was able to survive a travel to the event horizon, they would actually never reach it from their perspective as time would slow down for them to the point where it literally takes eternity to move but a micron.
False. From an outside viewer's point of view, it takes an eternity to get to the event horizon, but to a viewer who's falling into the black hole, time continues normally.
You got me there.
Almost
I shouldn't edit when in a hurry. Originally the sentence was about someone sending a probe to the event horizon but then I noticed that time wouldn't actually slow down for the observer. My edit didn't really correct that though or at least didn't convey what I was talking about.
In fact time wouldn't change at all for either of the two from each of their perspectives but the one approaching the event horizon would see the observer's time speed up while the observer would see the traveler's time freeze.
Now imagine the traveler being able to actually return from the event horizon to report their experiences to the observer. The observer as well as the universe surrounding the two would have aged quite a bit, whereas time for the traveler appeared to not change at all and neither for the observer.
Did time really not slow down for the traveler?
I'd say, the fact that the traveler didn't feel the effect of it, doesn't mean it didn't happen. It just depends on the reference frame. Including the universe (even if only to the point where the observer is) in the reference frame makes obvious that time must slow down for the traveler even if they can only notice that by watching the universe.
