I think the danger is that it's always "obvious" that the current fashionable tech works in analogous ways to the mind/brain. We can spend all day finding ways in which they are similar; for example how the brain does information processing and the CPU does too.
The point is, I think, people from the steam engine era had similar reasons why the mind/soul was exactly like a steam engine. I won't try to reproduce them here, but I'm sure there were convincing arguments at the time. Who has the awareness to claim, before the current fashionable technology becomes unfashionable, that maybe no, the brain is not a close match for an information processing machine? ;)
