This is pretty awful, as in mean. Why would you deliberately want to insult someone who hasn't done anything to you? If it's getting them back sure, but as sport? Just cruel.

  Despite all the equations, it seems to me that your work didn't require any real mathematical sophistication. Did I miss something? (This is an especially good ploy if you observe others struggling to understand the talk because they will not want to admit to that after you imply it was easy.)
  Isn't this just a straightforward extension of an old result by Hartmanis? (Not even Hartmanis remembers all the theorems Hartmanis proved, but everyone else will assume you remember something they have forgotten.)
  Am I missing something here? Can you identify any deep mathematical content in this work? (Once again, audience members who found the talk difficult to understand will be unwilling to admit it.)

  Wasn't all this done years ago at Xerox PARC? (No one remembers what was really done at PARC, but everyone else will assume you remember something they don't.)
  Have you tested this on the chip Intel got running last week in their lab? (No one knows what 
  chip Intel got running last week, but everyone will assume you do.)
  Am I missing something? Isn't it obvious that there's a bottleneck in the system that prevents scaling to arbitrary size? (This is safe because there's a bottleneck in every system that prevents arbitrary scaling.)

Reminds me of low effort "comments" on Show HNs. Now I'm thinking that maybe people were deliberately trying to be insulting. But why...? Especially when people are being vulnerable sharing their work....
