The issue with such software is that it's mission-critical. In other terms, it needs to be zero-downtime, bullet-proof, audited and certified by external actors and to be supported for the next 30-50 years.

Historically, all those limitations make the "move quickly and break things" approach popular in the current wave of startups impossible and the code with this kind of requirements has historically been implemented by large corporation already working in the industrial domain.

If anything, this feels a domain where GE and large contractors will be chosen to write mission-critical code over startups.
