Whatever system comes in during the next few years suffice to say it'll be different in many ways to its predecessor.
Different isn't always bad it just needs an open mind to adapt to it.
For better or worse (and it's very easy to find fault, quite another thing to find workable solutions) the system has enough of the right people in the right places to ensure the product coming out the other end will still be just fine.
The next generation may not be able to use astro-navigation and a dalton computer to navigate to Timbuktu and back but I reckon they'll cope fine with whatever is thrown at them. It's a brave new world out there.
Can our collective New Years resolution be to quit whining and just accept change?
