I would narrow that scale down to 50. Significant technological advancements can be attained between now, and fifty years from now.
Technological advancements tend to go at their own speed. Take nuclear fusion for example. When I was at school it was predicted that there would be commercial fusion reactors in 30 years. Much of the theory was understood, it was just a case of getting to grips with the technology. I left school nearly 30 years ago and where are the commercial fusion reactors? They are now predicted to still be as much as 50 years away.
Proving that these loopholes exist in no way means that the technology to harness them is close. It could be 5 years, it could be 500. Guessing at the first number that comes into your head is a pretty meaningless exercise.
