And so quite a lot of readers think there is some super duper smart guy offering this cool hidden insight that they can easily use, only to forget it by the next hour.
I think there are a handful of "obvious" interactions that should have been called out.
Politics + Space: Greater international competition for space-resources will likely begin, and we may see the end of first-come-first-serve orbits. The international inward-turning politics may be particularly poorly timed; we may see irregular military action in space.
Politics + Cyberspace: Inward-turning politics combined with greater awareness/impact of breaches (including on increasingly-autonomous vehicles?) will almost certainly lead to countries closing their digital borders a-la China. Its already been proposed in the UK, I believe.
AI: This is going to be the source of some huge wildcard, and I think everybody knows it. Companies have massive amounts of data on people regarding how they behave; eventually someone is going to give that data to an AI with the right/wrong instructions to make a noticeable impact on society.
Most "cool hidden insight" can be attributed more to the autor's writing skill (and acting skill if it's youtube talking heads) than to any actual useful info inside. Do not let yourself be mislead by Mr Stross' profession, most internet "experts" are even worse than that. And they don't even admit they're fiction writers.
