That slide deck is complaining that correct work on quantum attacks should be seen as negligible priority or as distractions. TFA is complaining that JVG isn't even correct. They are pretty different concerns.

To be clear, I think that slide deck will be looked back upon as naive. In particular, it makes the classic mistake of assuming the size of number factored should be growing smoothly. That's naive because 15 is such a huge cost outlier and because quantum error correction has frontloaded costs. See [1] and [2] for details.
