Lets face it, we are in an exponential technological curve,
go back 100 years, and probably 90% of stuff in your house
didn't even exist back then.
Actually, I think there are very few things in my house that didn't exist a century ago. There are a few important items, for sure: refrigerator, AC, microwave, computer, cell phone, CD/DVD players and associated media, automobiles. There are probably a few things I'm forgetting, but there is so much more than that in my house that's virtually no different than what was around in 1908: clothing, wood floors, ironing board, closets, stuffed animals, blankets, plates, silverware, drawers, photographs, tables, chairs, beds, doors (my house was built in 1924, so this list could go on and on and on). For that matter, I think the vast majority of things in my house would have been present in similar forms in any number of centuries past.
I think the prospects of medical advances that will lengthen lifespans is fascinating, but I also think people tend to lose perspective on how the times really aren't as different as they think they are. We end up thinking we're special because of the times we live in, and it's just not the case (no special criticism of you, of course - just an observation spurred by your remark).
