Its never immediately obvious. Computers put thousands of human calculators out of jobs. Now computers superpowered any and all physical modeling, molecule searches, etc. But, should we have decided eg astronomers or microscopists are required to have jobs, then we wouldn't have developed automated high quality optics, which themselves were required to commoditize computers. Almost all technologies somehow play a role directly or indirectly that existed before a new one for any new advance.
