People on Manifold and in related communities tend to have much shorter technology timelines than the mainstream. We debate whether general artificial intelligence is coming in 5 years or 50, while normal people are saying things like "will we ever get out of our solar system before the sun dies in 5 billion years? Eh, maybe." I've seen completely serious predictions that certain techologies are possible but will not be developed for thousands or even millions of years.

If, after the year 2100, some significant new breakthrough is found, this market resolves to YES. If that hasn't happened by 2150, and scientists and inventors have arrived at a consensus that we've already discovered all the technology and there isn't anything new to invent, this resolves to NO. If they don't have such a consensus by 2150, this market remains open until they do.

In order to count, the invention must actually be built; a blueprint and high confidence that it would work is not good enough. However I will make allowances for things that just couldn't physically be built in that time frame. (e.g. a galactic-scale particle accelerator would be limited by the speed of light to not being built for ~50,000 years, but that limitation doesn't mean that we haven't yet invented the technology. Same for a dyson sphere that's being slowly constructed over the course of hundreds of years due to having to shuffle material back and forth across the solar system.)
