Yeah, I'm pretty sure that the people who wrote ext4 assumed there would be ext5 (or something else) to take over way before 2038. If you look at the history, ext2 was released in '93, ext3 was released in '01 and ext4 in '08. If you told the developers in '08 that ext4 would not be replaced in 30 years time, they would laugh at you (or cry).
