But they really have to learn the lesson anyway. AN would not have been with the team forever, given his age. Also his bicycle accident shows that things may change heavily from one day to the other.
Don't get me wrong, AN was an integral part of the team. But like any other company, organisations evolve and it's the job of a CEO to prepare and empower the organisation for successions of certain individuals.
In RBR's case for sure it's rather a revolution than evolution given longtime employees (RM, AN, JW) will leave or have already left. Also the budget cap era makes it even harder to ensure stability when other teams come and make big offers.
It gives the lower ranks the chance to step up which is one of the very little positives.
For me the current cap system is very unfair to the lower ranks employees, as stated by ex-F1 engineers. If the system continues like that a lot of team may struggle to hold their engineers as they would earn more money in the non-F1 industry for less working hours... but I'm getting off topic
Back on topic: When you look at Dan Fallows & Peter Prodromou, not all ex-RBR-employees can do magic right from the start in other organisations.
So it will be interesting how the team regroups, how it will keep the competitive focus and hands-on mentality.
I hope it's an incentive for the whole Red Bull F1 organisations to show the F1 world: we can cope with that, we are a strong and united team and the top step of the podium is our main focus for the near and foreseeable future!
