That's a great analogy! For English (and autonomy levels), this works for orders of magnitude: Two and two and two and two and two, no good; ten times ten, good in easy things; with a thousand words, you can get things done and sound normal; a vocabulary of ten thousand words provides an adequate command of the language to discuss complex concepts; 10^5 or any higher exponent comprises capability exceeding that of a majority of users.
I do agree that we're still at level 2: it's relatively amazing (i.e. see what can be done with the limited toolset available), but not really that great: outside of predictable, menial tasks, the rough edges become acutely limiting.
