You will likely see Gates, Stallman, Torvalds, Lessig, Knuth, Norman, Minsky, Alan Kay, Abelson, Rivest, Sussman, [...] die in your lifetime. Sure, Turing, Church, Curry and others have already died, but their numbers are low compared to the ones that have not yet (and some of the older users here might actually have been alive at the time of their passing).

If you were in a field such as chemistry/philosophy/biology/etc., you would also be alive for the deaths of some eminent people in your field, but not in the same proportions.
