I must be a mind-reader. It seemed like a logical thing since so many cool things are coming out of it and like I said it shouldn't trigger your fears.

I don't see any evidence that you "are too dumb" for mechanical engineering or anything related. It is a matter of interest, time and of course money. Computers may be able to do math way faster than you, but they could never write Moby ****(Wow, I should have seen that coming), err A Tale of Two Cities. Robots are used extensively on automobile assembly lines, but they still require people to be on the lines to work alongside the machines. There is no robot or computer that can design a car or engine or anything like that.

As for writing, yeah it seems like it might be a hard thing to break into, but I don't know. However, because of technology all it costs is time, effort, a computer and an internet connection. Plus, self-publishing, whether it is e-books or publishing on a blog, is easily done. You can work a day job and be a writer. You never know, if you write enough you might find you won't need a day job.

That is the only reason I do not regret getting a BS and MS in Computer Science since I have been unemployable for 6 years and counting. I have the theoretical background to do just about anything in the field and it has the same barrier to entry as writing in most areas. Granted, I am not going to be writing an operating system or an office suite to compete with Microsoft but there are a lot of areas that are doable by myself. My computer and internet connection is all I need to get started. I do have several programming projects underway but on a good day I can focus for 2, maybe 3 hours so progress is slow.
