Futuristic-Utopian Technology For Perfect Lives?

I'm curious what kinds of technology any of you who are worldbuilding a futurist utopian setting have in place that would give the citizens of this world or city a near perfect life?

I'm a bit stumped and drawing blanks, so I'm just making this post for some inspiration. What I was thinking of for what I'm currently working on is a city where there are no real problems for its inhabitants or whatever.

The city I'm building is situated near mountains, so I was thinking of a sort of technology that would either warn or completely negate the city from the effects of avalanches or extreme blizzards. For specifically avalanches, what came to mind was having the city be retractable underground, kind of like Tokyo-3 in Neon Genesis but that seems like a bit of overkill, but other than that my brain is completely drawing blanks for what I should add in terms of technology, and I was wondering what kinds you all have in your worlds for inspiration.
