When does the author claim this? He says the probability could potentially rise, and doesn’t make any claim as to the actual value of that probability. Just that it could increase instead of decrease due to some factors others haven’t considered. I think it’s one thing to say “the value x could increase instead of decrease” vs “I claim that x is y”
