I suspect (but cannot prove, of course) that we still have MUCH to learn about the genetic code. These attempts to "simplify" the genetic code and start from a tabula rasa are based on a failure to understand the fundamental nature of genetics.

What we know today will be as laughable in the future as the Ancient Greek's ideas of subatomic particles seem to be now.

To dismiss 90% of the genetic code "because we do not understand it" is a brave and foolish move. It is that 90% that determines how cells actually work. To "strip down" the code and try to make it run with only 10% of the information content is hopeful at best.

In the "bad old days" of computer programming, code was written in incredibly complex overlapping patterns, re-using the same code for different purposes multiple times. I rather suspect that the genetic code is similar (although it has not been "written", but has evolved). It certainly has some redundant parts and some "wasted" space, but the DNA code has some incredible secrets to tell us, once we understand enough to "hear" what it's saying.
