Still, over time it should become more likely to meet Bf, not less; there are more people in general, and more documentary filmmakers, adventurers, tourists, infrared cameras, planes etc
Except if they died out. However, someone should at some point also find bones.
It is quite possible though that over time there are fewer and fewer BFs. They might be going extinct, even without much human interaction. As for finding bones, if the population is low, and their territory so big, it might take centuries.
