Their mode of replication differs, as each new guess in genes must be neutral or positive for the vehicle. This makes genes slower, but that's IMO a quantitative difference, not a qualitative one. Pure genetic knowledge could colonise the galaxy, it'd take much longer than with memes.

I don’t think that’s true. I remember Deutsch saying something like this but I think he’s confused about evolution.
Not every genetic change that isn’t an improvement or neutral is automatically deleterious. A replicator could go through a series of changes that temporarily reduce its ability to spread through the population until it undergoes another change that raises that ability above the original level.
