I don't know if thats accurate. Supposedly, tech hasn't killed vehicles ownership either for Millenials, but it sure looks like it's helping dig the grave:

"Because millennials use technology in every facet of their lives—from mobile phones to tablets and laptops—to connect with friends and family and to get work done, the tech gadget is their most prized possession, and has a much higher value to a CMC than transportation or owning a car. Think about it: while CMCs are likely to share a car and a ride, there’s no way they would ever share their phone.
CMCs game together and hang out virtually, they don't have that same need to physically get together as prior generations. The CMC’s popularity and relationships are defined by their online status, not their "cool ride" and they make all of their connections online. millennials search for jobs online. They prefer to coordinate dating online, and meet people through websites and apps."
In all honesty, tech probably is "digging the grace", so to speak. The blurb I mention from the article goes on to illustrate how an expensive vacation, shared via photo streams and status updates on social media, is probably displacing the "Check out this jewelry I got! U jelly?"-type of conspicuous consumption people used to partake in.
I noticed that you called that out in another comment. Fully agree. Status is never going to disappear, just change forms. Kudos!
Well, strictly speaking, we don't usually have to wear clothes. In the modern urbanized lifestyle, clothing serves almost no important function during warm weather. The main reasons I wear clothing during warm weather are social and legal pressure, not pragmatism.
Although if you s/clothes/suits, then the argument would probably be true ;).
A cold-adjusted human can easily deal with 10C without protective clothing (at least for short periods), and human heat-resistance actually improves without body-covering clothing. (Clothes impede the effectiveness of sweating.) Any hot environment humans can handle without AC, they can also handle without clothing.
Just look at any of the african tribes that either wear an insubstantial skirt of some kind or wear nothing at all.
So what you're saying is... you gotta wear clothes?
Not that I agree, but it's not like he said the same thing in another way. He tried to make a distinction between having as ("we must") vs ("society makes us").
So imagine my delight when, of course, someone did.
If you only count "saves us from low temperatures" as important and not "enabling me not to see most people's genitals unless we're in a romantic relationship".
Why would I want to see, say, anybody's testicles or someone's half-wiped ass while I work? Even tits, which I'd normally like would be more of a distraction (and no, it's not due to not being de-sensitized to them: you can never be de-sensitized to tits).
There's an underlying premise here that "cultural doesn't really matter" or that we should just do what's a biological necessity.
As humans, we do most things because of cultural reasons, or in other words, because we collectively came up with some rules/trends/fashions/etc. We're not mice or ants to just do stuff because of biological imperatives.
Obviously, though, tech has not killed the jewelry industry. Jewelry suffers from being the fashion industry at it's most reductive: all form, no function. That is, we all gotta wear clothes, nobody's gotta wear jewelry. There's probably quite a few cultural changes all hitting the jewelry industry at once: people are marrying later in life than they used to, it's taking younger people longer to become financially stable than it used to, and what counts as a good gift isn't what it used to be -- the article itself says as much:
"But it’s not all Kindles and iPhones; according to the De Beers report, millennials are choosing to spend their dollars on experiential activities over luxury goods as well."
