The estimated 50% chance of human population collapse between 2140 and 2600, seems reasonable. Our power to destroy ourselves with weapons or accidents, or use biological and information technology to productively enhance or replace ourselves is growing at an exponential rate. Any scenario where humanity reaches the year 3000 without either having destroyed ourselves, or enhanced ourselves beyond recognition, seems unlikely to the extreme. The only scenario I can imagine where radical technological change does not result in a radical change to the human condition is if a totalitarian government managed to enforce a no-progress civilization for hundreds of years. I am marking the years 2140-2600 on my calendar so I can remember to look back and review the results of this prediction using my post-human thinking apparatus. Hopefully I didn't extinct myself.
