I do, because it perpetuates this rubbish:

Why the hell do you keep saying I'm passing myself as an expert, and have made grand claims?? I have claimed very little in this thread. Pretty much just:

1. Observation that supercomputer procurements include useful work.
2. A couple of simple observation about general makeup of top500 list.
3. Referencing FFT code and paper.

From there, made a handful of pretty rudimentary inferences and/or guesses based on these, and present them mostly as questions to your claims, rather than as trying to pass them off as rigorously developed fact, or expert judgements.

Compared with the paragraphs you've written here, each of my facts or inferences could each be shown false or put in doubt, with in a sentence or two. But oh no, you don't like my tone and I'm anonymous and I should be fired, and when you were a teacher young whippersnappers like me... , and mockery about what conferences I didn't attent, and I don't know anyone who makes fusion reactors, and you already proved everything on some other mailing list thread, etc etc.

Stick to the argument and not the person, for pete's sake. Really, just dispense with the waffle.
