Right. So the general says we should use a different weapon. That’s fine. It’s also fine to question if that strategy makes sense.

It is nonsensical to say “the general can’t hit a moving target with the old rifle, so he should say nothing at all about weapons”. Which is what the person I replied to said.

The point the person you replied to was making was that him being CTO didn't add much credibility to his claim as you seem to assume by bringing it up, not that it necessarily removed credibility.
