No, we don't really understand infinity. We don't even know what is an infinite in our reality, unless I missed some really important news. You can understand perfectly infinity in the mathematical abstraction of reality. You can use it for renormalization or whatever theoretical instrument you want, but please don't tell me that you know everything about infinites when all the empirical observations at the moment go against an infinite universe and an infinitely divisible space-time that is probably discrete rather than continuous. Stepping back in topic, from my point of view of a completely amateur physicist, I really appreciate her work. Whoever contributes to spreading knowledge is making the world a bit better than it was before (B.P.) I wish there were more people in the world keen to explain things rather than ridiculing others just because they don't understand something that for us is very obvious. Just my two pence.
