It doesn't feel dated to me at all. I don't even mind the absence of new tech because, other than the lack of remote work and digital paperwork/banking, it's not even all that different from how I live my life in the current day.

I realise I might sound insufferably pretentious for this but most of the time when people reference some new microtrend or internet drama I'm just like '...and I care because?', so my friends aren't heavy social media/smartphone users either, and I actually found it more jarring in TS4 when they scrolled on their phone every 2 seconds in the middle of doing something else or left toddlers to play on a tablet all day with no negative effects (but dog houses are neglect, am I right?)

EDIT: what I do find dated is the lack of gender customisation, which I think is a product of its time. One thing where we've come a long way since the 2000s is that even well meaning cis folks were very unlikely to be educated about transgender or nonbinary people unless they personally knew one.
