I think much of the hype around various scenarios where the output of the software is used directly for anything much, is just hype. I think most of the impact will be (as it has been so far) in people interacting with the software personally, in order to get ideas, brainstorm, just have fun, and that sort of thing. I'm sure there will be a ton of mediocre text posted, but there already is; this is just a matter of degree. I'm rather optimistic that the negative impact will be limited.
