That is not a crazy idea because we know for a fact that in the entire human genome
there are only 3 billion base pairs. There are 4 bases so each base can represent 2
bits, there are 8 bits per byte so that comes out to just 750 meg, and that's enough
assembly instructions to make not just a brain and all its wiring but a entire human
baby. So the instructions MUST contain wiring instructions such as "wire a neuron up
this way and then and then repeat that procedure exactly the same way 917 billion
times". And there is a huge amount of redundancy in the human genome, if you used a file
compression program like ZIP on that 750 meg you could easily put the entire thing on
half a CD, not a DVD not a Blu ray just a old fashioned steam powered vanilla CD.

Just want to point out that the process of DNA expression is highly dynamic and is
multi-factored (including environmental driven epigenetic feedback). This is especially
so during the process of embryogenesis, an unfolding developmental choreographed
switching process that is controlled by epigenetic programming
(methylation/demethylation and other mechanisms). The mammalian genomes undergo very
extensive genomic reprogramming during embryogenesis.
DNA is not a direct single layered – single meaning -- instruction set encoded and
fixed. The expression of hereditary information is a multi-layered, dynamic and
epigenetically influenced (driven) process, and this is especially true during
embryogenesis. The same strand of DNA, depending on the dynamic action of the large
number of transcription factors (there are 2600 identified proteins in the human genome
that contain DNA-binding domains and it is thought that 10% of our genome is involved in
encoding this large family of transcription factors) can encode very different mRNA and
result in different outcomes and be used for different purposes.
It is – IMO – necessary to understand DNA as an encoded bundle of potential instructions
that through a highly dynamic transcription process becomes actualized.
The actual expression of the underlying DNA blueprint is best understood in terms of it
being a dynamic, environmentally and developmentally influenced process. DNA is
arranged… and re-arranged – read forwards or backwards with coding sections turned on or
off – in a large number of different ways.

But all the information for that back and forth on and off transcription factors, binding
domains, etc. has to be either encoded in the DNA or extracted from the environment.
