#2360·Erik OrrjeOP revised 14 days agoThey are the same knowledge in terms of encoding knowledge about the environment, and possible transformations based on that. That knowledge can differ in reach (context independence/how fundamental it is).
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.
