The article states that infinities in Quantum Electrodynamics is viewed as renormalization problems. However, it is my understanding of Quantum Field Theory (QFT) that infinities are not just a matter of a renormalization problem but a necessary property of the condensate - otherwise the theory would not work at all.

So if my understanding of QFT is correct, what does that leave us at?
