I don't think retail is dying as such with the move to online shopping. It's just that the kinds of jobs we require to support online shopping are different to what we needed for bricks and mortar shopping. We used to need shopfitters and signwriters, but now we need web designers. We used to need commercial landlords, but now we need web hosts. We used to need sales staff, but now we need warehouse staff to pack and ship orders. It doesn't mean that everyone's skills transfer directly over, but there should be room for everyone, at least in theory.

PPS - And, I guess, figure out what those jobs are.
