If people come to the conclusion that the NSA is likely to develop and AI while being aware of the danger of uFAI, then they would write letters or seek to start a movement to ensure that any AI the NSA—or any government organizations, for that matter—would ensure friendliness to the best of their abilities.

I think your idea of a democracy in which letter writing is the way to create political change, just doesn't accurately describe the world in which we are living.

Five years may be the time it takes for the chain mail to effectively popularize the issue to the point where the pressure is on to ensure friendliness, whether we solve it decades from then or not. What is your estimate for when uFAI will be created if MIRI's warning isn't properly heeded?

If I remember right the median lesswrong prediction is that singularity happens after 2100. It might happen sooner. I think 30 years is a valid time frame for FAI strategy.

That timeframe is long enough to invest in rationality movement building.

That is not a valid path if MIRI is willfully ignoring valid solutions.

Not taking the time to respond in detail to every suggestion can be a valid strategy. Especially for a post that get's voted down to -3. People voted it down, so it's not ignored. If MIRI wouldn't respond to a highly upvoted solution on lesswrong, then I would agree that's a sign of concern.
