I simply don't believe any past statistics on things like this are relevant in the modern era.
Every generation thinks it invented sex, rebellion, and curiosity.
So yes, we can do all this stuff better, faster. It makes for a huge difference in degree and if that difference is large enough by itself it becomes a qualitative difference.
But I think the mistake is to think that a change like that is enough to significantly decrease or increase our ability to build empires or to destroy them because those forces tend to balance out (assuming both sides have roughly equal access to the technology).
That's why none of the other technological advances from the past made a huge difference either, the 'empire' that was expanding brought their technology with them, it became adapted and then was used against them or they simply regressed.
The only times it worked was when the natives were entirely slaughtered or intermixed and those countries typically ended up declaring independence.
Empire building is a losing business in the longer term, and there is no proof to date that a complete and unobstructed view of the world or instant communication are a key element to empire success (or failure).
But since you're framing the argument in terms of ignorance and such I think I'll bow out here.
Its about maintaining an empire, which i think is an important distinction.
I dont see the US waging war against anyone who is trying to dethrone them as a superpower. The ways that other countries are trying to dethrone the US are much more economic.
Economic war can be waged over the internet quite well, without any ships or smoke signals.
But, I don't think the Ottoman, Chinese, Arab, Hitite empires give us any predictive information for the longevity of the later ones.
I mean, history does show pretty convincingly that "stuff ends" eventually. It's got some examples for how, they are usually fairly specific and unclear. Europe has been obsessively theorizing about The Fall of Rome for 1500 years. All those musings really tell us about is the people doing the musings. It was because of Debauchery, Christianity, Tyranny, Civil Strife, Monetary Policy, Cultural Purity, Military Discipline etc. etc. depending on who you are.
I bet you can guess that Victorians suspected orgiastic debauchery while Marxists suspected class structure.
