If in some dystopian future, the C-levels could be given 2 years for what could amount to a basic human error in an otherwise well-run organisation, no-one would do the job and a whole sector of the economy would probably go bust.
Having worked in a handful of companies, at least some of them try to do the job properly but are restricted by employee turnover, lack of consistent skills across the software sector, negligence at any level, incompetence - even if not malicious, tired engineers, ancient software systems that would be impossible to replace in any reason time etc.
