The following questions were put in discussion:
Shantanu: does this argument also apply to Starobinsky's 1980 model of inflation?
Shantanu: you have mentioned this, but for your argument to hold true do you need to assume Bunch-Davies vacuum?
Shantanu: a more general question. so now is the whole concept of inflation ruled out? (since multi-field inflation potentials are also inconsistent with Planck).
