> cheaper at a geometric rate

Citation needed - my company is paying more than ever for code generation. I have no reason to believe (given anecdotes) that anyone finds themselves in the opposite situation.

It keeps getting cheaper and better -- for me.

I get a lot more use (read: cheaper per interaction) and much better quality results from the $20 that I spend on this stuff every month than I did several years ago.

(And several years before that, it was all essentially unobtanium.)
