Are you trying to imply that the JWT is not fit for its mission to deliver meaningful science? Because that's not at all what the article you linked says. It just says Zurbuchen admits that there's a lot that could go wrong.
Nothing, to me, indicates "almost sure failure." Just a realistic overview of the risks.
That's kinda what it's implying though. You can't outright say "yeah this thing is doomed from the start" (unless you are Elon). But you have to shape the audience's expectations. "There's a lot that can go wrong" "high risk" "many single-point failure events that have to go off perfectly" etc.
