That isn't deceleration, you've just chosen a very selective way to compare. If you use time as a denominator, which is kind of intrinsic when talking about rates of acceleration, you get a very different result. If you graphed .3, 8.9, and 104.4 on the y axis, with years on the x axis, it would be pretty clear that there was in increase in the rate of progress.
We went from adding 8 teraflops in a decade, to adding almost 100 the next decade. If we add "only" 400 more teraflops in the next decade the graph will make that initial growth look flat in comparison, even though your math would show that we are basically stalled out.
It’s like claiming that a company that goes from making $1 to $1k to $100k to $1mm in a 4 year period has decelerating growth.
