Indeed. Based on current mortality statistics[1], only 2% of us would manage to live 10,000 years without succumbing to accidental death of some kind, and the number that would make it 100,000 years is just vanishingly small.

EDIT: This is more a consideration with respect to "cure for ageing"-type advances, not so much the mind-uploading scenario.
