Most of the comments here are assigning this as Plato's opinion.

I'd just like to point out that Plato very rarely wrote in his own voice so it's very hard to say if it's his views or not that are being expressed.

In this case however, this is almost certainly an expression of Socrates' views, not Plato's. Not only because it's in the voice of Socrates but also by what's transparent in their actions: Socrates didn't leave anything in writing and Plato left us arguably the most important written corpus of classic Greek philosophy.

Maybe he felt ambivalent about it, but he certainly thought there was a value in the writing.
