You're right and I agree with you to an extent. Also as of now the tools aren't quite intelligent enough for one to produce software of that complexity without having someone competent at the helm.

That being said what already exists was already enough to shutter the stock prices of many software companies precisely because the fear is that their clients will just re-create the software themselves instead of buying it from someone else.

I guess we'll see how this will pan out in the next few years.
