Thank you for this question! I am glad you ask.
I do not want to spread FUD but we will all be dead by then ;(
Sidenote because of these lines of code i started coding:
int64_t nSubsidy = 50 * COIN; // Subsidy is cut in half every 210,000 blocks // which will occur approximately every 4 years. nSubsidy >>= (nHeight / 210000);
