In a web article at http://members.cox.net/johnsuzuki/softfail.htm - it is noted that only 16 percent of the initiated projects succeed, and that 84 percent are not delivered on time and under budget if ever at all. Googling "software failure" vs "software success" yields 50.8 million vs 20.5 million instances. It is not a statistic that those who work in the industry can be promoting.
It may be due more to high expectations and low levels of testing implementability and the failure to establish accountability and achievability standards. It seems as long as someone who owns some gold and wants to spend it on a software solution, there are always those who will for some of the gold, step up and say "We'll try to do it"(WeWillTry). The gold owner is often satisfied with this rather than the requirement, "There is no try, there is only do". (You forgot "or do not"!)
