> It's also a bit presumptuous to assume that a future authoritarian regime wouldn't have expert technologists at their disposal...
I think your thinking here is too binary. Clearly there exist possible futures where authoritarian governments are hyper-efficient and have brilliant technologists advising them. In those futures we're clearly doomed and thus we might as well give up now. The thing is, those futures are not inevitable. There are also many (IMHO more realistic) futures where governments are messy and inefficient (like they are today), where their authority is blunted by organizational and jurisdictional issues (as it is today), where their technologists are not hyper-competent (believe me, as they are today.)
In those worlds there is a huge difference between a scenario where the full weight of FAANGM's resources is pushing to build massive data repositories, and one where they've taken firm technological steps to limit it. We are in the first world and we should be in the second one.
> Issuing an edict to "do things like you did them in 2022" doesn't exactly require genius-level administrative talent...
I think that this will actually be more difficult than you think: this is why governments are spending ~millions right now to slow down the deployment of new encryption technology [1]. But stop worrying about 2022: what you should be worried about is 2036. Look at what we've done to privacy since 2007 -- the year the first iPhone launched. Now imagine someone from ~14 years in the future coming back to to explain what Silicon Valley has done with even better technology like wearables and powerful ML tooling. When you're in a hole, the most important step is to stop digging.
