There's an element of truth that a certain number of people really didn't put up much of a fight when Jensen fluttered his eyebrows at them
But there's also a lot of history of AMD in recent years over-promising/hyping and delivering damp squibs.
I think for some it's not so much Jensen being their knight in shining armour, but rather having completely depleted faith in AMD to deliver something of comparable quality.
Yes there might be certain amount of impatience amongst some.
But I think AMD's impressively poor marketing over many years and poor track record in recent years when it comes to being competitive... people remember this and expectation from AMD is probably at an all-time low, really.
