If the philosophical meaning of "real" admits that computers, the Internet, and the GPS system are real, then I don't see what grounds it has for rejecting that things like transistors and electrons and other such underlying things are real as well, since transistors and electrons and other such underlying things are what we build computers, the Internet, and the GPS system out of.

If the philosophical meaning of "real" casts doubt on whether computers, the Internet, and the GPS system are "real", then why should we care about it?

If science hasn't, then neither has anything else.
