You could divide "your future" into two paths, conservatism (not the US amalgamation) and "missing the times that'd been", or continue move forward and adjust as the world change, which it always will, both in positive and negative directions. Things are changing, this is hard to disagree with, even if people disagree how things are changing, most people probably need to rethink a lot of their assumed perspectives, as I too had to do, faced with what I believe to be new realities.
I don't feel like it's patronizing to remind people about achievements they've accomplished and that they're still a capable person. Nothing we say to each other here on HN should be taken as "This is how you must live you life" but more like "Here's is something I hope helps you, if not, no worries", as we hopefully assume good faith out of each other.
