alt Hacker News> this article is about the philosophical meaning of the word "real".
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?
> from that viewpoint science hasn't delivered yet
If science hasn't, then neither has anything else.

you are confused.
the question is about what does fundamentally exist, not what you perceive through eyes or experiments.
do particles exist or not? is it all just in your imagination because you are a "brain in a vat?" what about the everettian multi-verse, is that real or not?
by saying these SCIENTIFIC questions are trivial to answer because you can hold a GPS receiver in your hand is to completly misunderstand what is being discussed here
nobody said something else deliverd on this question. but neither did science. it's the consensus in physics right now that it can't say what "really exists", this is not a fringe position
It does neither. The philosophical meaning of "real" is exactly the process of exploring the various possible definitions.
And it leads to the observation that our experience of reality is not objective, not absolute, and is likely very species-specific.
A cat can sit on a laptop without understanding the laptop or the Internet. All it experiences is a warm object
Is it rational or realistic to assume we don't have analogous perceptual and conceptual limitations which - of course - we're not aware of?
