Sure, but maybe it's inescapable.

When we recruit for a job, we first select a candidate from CVs and interviews, and only once we've chosen a candidate do we begin training them.

Do you think it makes sense to strive for a recruitment process that will get perfect results from any candidate, so we can stop wasting time on interviews and just hire whoever? Or is it inevitable that we have to select among candidates before we begin the training? Why should it be different for computers?
