Code Accountability - 2026
In the year of our Lord Claude Code I think it is important for reasons of fairness that if a human won’t review their own AI-generated code, we cannot expect other humans to do so either. The time required to conduct a thorough human review is much higher than the time it takes Claude to generate tens of thousands of lines of code. This wouldn’t have been a problem if it were trivial to…
