Didn’t you read the part about how they had to pivot at the last minute? And the performance increase was relatively small that year as a result? And how the team was restructured? God, the Kool-Aid drinking in here is unbelievable.The framing of the issue as "setback" and failure is so sensationalising, not making it clear that part of research and development HAS to involve experimentation (DUH!) and various trials and errors. I wouldn't necessarily call it a "setback" which is too sensational and tries to capture the audience's mind in a particular way. Boo!
Anyone who has done any serious research and development will recognize that testing, development, and various failed approaches is part and parcel of the work.
