Software has neither gotten worse nor become any better. All you're seeing is the cost of writing code approach near zero. As that happens the speed at which you see defects increases. Software is by its very definition "malleable". It is without (or very few) constraints. So it is very hard to get "prefect". That is why IMO Site Reliability Engineering will be one of the few fields that will remain, because until we build an _actual_ goodness to gracious Intelligent System that can think critically, including how systems can fail (which includes humans), software will be what is hat always been "soft".
