Surely Red Bull does not have that history, reputation and speciality of Mclaren for now but I won't say they will "never" earn it. They contributed great drivers and moments to the sport, saying this as a Fernando fan, witnessed two titles slipped away to a quicker Red Bull.
On topic, I definitely do not have that pessimism about Mclaren and their current development effort and process. I am sure they will earn success again but I can't hope more for it to come as soon as possible.
