What type of businesses are you talking about here? Non-software or just non SaaS?
So my belief is that those areas are actually void of progress, because 'software' took the intelligence that would have been applied to other areas simply because software often paid 1x-5x more in salary.
But now software, in both profession and product - is becoming overly competitive, and will become top heavy with engineers 'stuck' to move forward (in areas of innovation). One can easily see it in what the industry produces to show our phase - the low hanging fruit is gone. Progress is much less innovation, rather than efficiency, measurement, and tooling. Efficiency is like pulling in an MBA to remove the cruft - one can mostly expect linear, smaller gains.
