If a bridge falls down and people die, the suits go to prison for criminal negligence for not hiring experienced people and giving them the power in the organization to set the schedules. If a system that involves software fails and people die, the courts throw up their hands and say 'nobody knows how computers work, and there are no standards we could claim they violated or ignored' and the company usually doesn't even take much of a PR hit. It should be obvious to everyone that this situation will not stand forever and it will be very bad when it stops... but everyone has motivations to resist the establishment of standards so they'll continue to bicker about it and do nothing until legislators force the issue in the most hamfisted and horrendous way possible.
