Yes, high information density is a very mixed benefit IMHO. The higher the density the more likely a typo will produce valid, but incorrect code. How may man-centuries have been wasted tracking down C++ bugs caused by confusing logical equality with assignment?

Those of us who are engineers rather than mathematicians recognise the value of a little redundancy!

For code writing at least, if you can type while thinking, all you
need is to be able to type faster than you think. Once either your raw
typing speed combined with the language information density reaches
that threshold, you don't need more information density. For me, Lua
is dense enough, be it because it's quite succinct, because I  type
fast enough, or because I'm a slow thinker. Information density is
only part of the problem.

For code reading, if you have to take into account the background
experience of all potential audience, I'm not sure there is a single
solution (or even a good one).
