2038 bug is going to be way bigger.
Y2k was largely, though not exclusively, a Cobol thing.
Unix time will overflow sign 32 bit integers in 2038, and virtually every computer program in the world relies on Unix time. Virtually all of them will be running on 64 bit hardware by then, but there are millions of databases that will have to have their schemas migrated.
He's referring to the 1970 based "epoch" where some computers calculate time based on the number of seconds since Jan 1, 1970. In the year 2038 that number will exceed 2^31 which means any computer still running in 32 bit mode will think time has been reset to 1970.
We don't have to worry about that because Google robots will have eradicated the human race by then.
