Software is already too ambitious. It's beyond our ability to write correctly, reason about or manage securely. When we can get to a point where we don't have a level 10 CVE every other week or millions of people's private information leaked constantly, maybe we can talk about getting more ambitious.
Who is “we” here? Every company and individual out there? Do you anticipate a solution to these issues you mentioned that would work to solve all the world’s problems?
Let's be more ambitious with the scaffolding and tooling that makes software correct, secure, and easy to reason about.
