I was going by the article, which called it a crew mistake, but either way, the computer was powerful enough for the correct procedure.
To me, more powerful is likely to imply more complex, and that can also offer more attack surface for bugs and mistakes, so to speak, and at the very least requires more work to prove correct.. so to just make it more capable than you actually need, just in case, may not always be the best choice?
In any case, my point is that a somewhat more powerful computer would have tolerated this problem while the real one did not.
