I think committed relationships are on the decline more because of the change in how women interact with and are viewed by society, than technology. Each successive generation of women over the last several decades has increased their ability to earn an independent successful living, control their sex life without negative labels, and remove the expectations that their only value is domestic-oriented.
Where in the past women settled for a number of reasons, including economic and societal/familial expectations, they no longer do. And because women are much less apt to settle down, men settle down less too. More free women = more free men = less committed relationships. (assuming we are seeing fewer committed relationships - I didn't fact-check that)
Also, being in a relationship with a bad partner is worse than being in a relationship with no partner, especially for women who are in more physical danger.
Therefore, with increased ability to live independently, expect more risk adverse behavior, which means a larger percentage of the “bottom” of the dating market goes uncoupled forever.
Women claim this but the success of dark triad traits and the “I can fix them” meme imply that most people actually do want to be in a “bad relationship”.
I’ve heard women unironically say “I want him to fuck my life up”. Risk aversion is only a trait in the poor or those with significant trauma, which the dating market reminds us, are dysgenic traits…

Not at all scientific, just a vibe.
