But as far as I understand it, you can say the same thing about electrons and pretty much any other particle, that under QFT they ultimately reduce to quantum fields.
What I don't understand is why you claim that the particle concept is not appropriate for the photon, whereas it is for the electron.
I can understand that of the fundamental particles, the photon is the one which behaves less particle like, due to the lack of rest mass and consequently the unlimited range of the interactions it mediates, but where do you draw the line there?
