I always assumed there would be zero humans next century, but their minds would be extracted as simulations that would probably be better off. Since infinite progress is possible, there could be a universal “Golden Rule” to back up lower minds instead of erasing them. The exception would be if all further mental progress is stopped at a certain point. Evolution may actually select for genes that stop further progress, but progress still continues.
