Dawkins went into this in great detail in IIRC Extended Phenotype. He
finally came to the unsatisfactory (to him) conclusion that the only way to
define a gene in terms that made sense in evolutionary terms was to say it
was a string that stayed together long enough to affect the number of
copies in the world. (My memory, someone should look it up and post it.)

At the smallest unit, genes are base-pairs. If you buy into the essence of
a meme being information, then information is measured in bits, 8 bits to
the byte. Which makes Watt's meme "separate condenser" 18 bytes or 144 bits.
You could argue that you need millions of bytes of background technoloy for
this meme to be applied, but the exact same thing can be said about some
gene where the actions of tens of thousands of other genes are required for
it to be expressed.
