What do you mean by "everything is turning into software"?
Also, while I agree that there's effectively infinite demand for new software (I can't imagine a day where all software companies and open source projects stop writing code), it doesn't mean that there's infinite room for new software businessnes -- especially the ones that start with a few hackers in an apartment cranking out a webapp in 2-4 months.
