you can not.
just think about it: 80 to 100 years uptime, no reboot, no fall back system, not even a cold spare. and you want to change something while its running? madness! maybe if you are very lucky you may be able to replace some of the internal components… but not to upgrade, only if your on the risk to loose the whole system…
First of all: Do they want to make real live friends? having only internet friends doesn’t sound too bad, does it?
you don’t get a friends from a single event. give it more time. much more time. some other comment mention hobbies or groups, and i think this is the key: you don’t go to those events because you want to make friend, but because of you interest and you make friends by accident. Don’t pressure it!
