Tangent: I thought you were going to hate the inflection point metaphor (and hence started your post with a pun about it).
The point being inflection points mathematically speaking don't usually imply a peak, rather a change in concavity (which might still be increasing).
It would be better for people to say something like "...it feels like we reached a high water mark..." to stress they worry about a certain maxima being hit.
Well, you can't change to concave down without eventually either hitting a maximum or another inflection point, right? Could be apt, given that most big tech companies are still growing in strength, for now. Just not as rapidly.
