The beauty of "rubber brain" is that it conjures up a different mental picture for each person. As far as I know the term does not pre-date the invention of rubber.
Concerning the topic of paid agitators on forums; I could use the money. "Have 'Puter, Will Travel".
I do not know that I could immitate a woman's voice convincingly enough to get the customer hot and bothered on the phone.
(I do hope that you know that I was joking about needing money?)
I am surprised that you would consider "rubber brain" as deep thought. Sorry to soar over your head with an everyday expression.
If ALL words conjure up different mental pictures for each person, then why would you ask me to explain this expression? Do you just want to send people on meaningless tasks to suit your pleasure?
(How much beer are you going to consume this evening? Maybe you should limit your consumption for now or your head will eventually slump onto the keyboard and the next thing that you know it will be Sunday morning.)

Because I pictured a novelty rubber brain, and even Googled it myself thinking it had some hidden meaning that I was not aware of. So I asked you what you meant by it. To which you never answered. "Rubber brain" may be a common word in the circles you hang out with. It's not in mine.
I don't drink beer, so your extended insult is meaningless to me.
What?! Liberals are the ones who want to dictate to everyone else what is good for them and what they should do. Conservatives are for limiting government in the lives of people.
Please quit drinking.
