re: Will humans still exist in 100k years from now…

Rest easy. There will be no humans on this planet in a 100k years. The current population will diminish greatly once we run out of fossil fuels. Technological progression will be reduced greatly after this, back into another feudal era. But some militaristic tribe will develop some bio killer that will inadvertantly wipe all of homo sapiens off the face of the planet.

Mother Earth will again prevail. And the cycle of life will recommence.
