Not at all, actually. In fact that's the opposite of what I'm arguing. There are countless things left to invent. It's just not worth doing most of the time.
As a trivial example, Unicode is not a 100% perfect text encoding scheme. Why don't we have something better than unicode? Why is there no interest in making a unicode-but-better format which solves all the problems with unicode? The reason is, unicode is sufficiently good that the cost of switching would outweigh any marginal benefits.
