According to an expert source cited by Andrew Huberman, Instagram is effectively the world's largest dating app by an enormous margin, with much of its time spent in DMs that lead to real-world meetings.

Huberman reveals that Instagram is reportedly the world's largest dating app by a wide margin — a fact that recontextualizes the infidelity risk of social media entirely. Eastwick then lays out two simultaneous processes at work in committed relationships: the derogation of alternatives (happy partners rate attractive others as 'weak sauce') and the 'playing with fire' of seemingly innocent messaging that escalates. [1] — Paul Eastwick "When you're in a happy relationship, your brain downgrades alternative partners — you see them as less desirable than anyone else would. It…" 2:06:40 He also cites recent studies showing that attraction to an alternative can rebound and increase desire for one's actual partner — the data behind Esther Perel's framework. The key distinction, Eastwick argues, is between the fact of attraction (unavoidable, not dangerous) and the repeated follow-through on that attraction (what actually erodes the protective mechanism and creates infidelity risk). He adds a practical note: couples can benefit from acknowledging the reality of attraction without acting on it — a form of healthy compartmentalization.
Take every measurable trait two people have in common, run the math, and your ability to predict whether they'll click is barely better than random chance. Dating app compatibility algorithms are built on a premise that the science doesn't support.
Objective similarity measures — the kind dating apps use to match people — predict whether two people will click at barely better than coin-flip odds.
When you're in a happy relationship, your brain downgrades alternative partners — you see them as less desirable than anyone else would. It's not delusion; it's a built-in protective mechanism. And it's why the marketplace metaphor for attraction ultimately breaks down.
The danger in infidelity isn't the initial moment of attraction — it's the repeated follow-through. Each subsequent conversation with someone you're attracted to erodes the protective mechanism that keeps your partner at the center of your desires. Instagram made this process frictionless.
Recent studies show that when people in relationships experience attraction to someone else, desire can boomerang back and increase feelings for their actual partner. Esther Perel has described this dynamic for years. Now it has data behind it.
Sam's initial MVP was coded in approximately one week using ChatGPT voice mode and copy-pasting code, with no prior technical experience.
Sam argues Discord is 10x better than email for building relationships with younger users who rarely check their inbox.
Sam's monthly operating costs include Cursor ($200), AI image generation ($100), AI video generation ($200), hosting ($100), email marketing ($80), and AI compute ($300–$500).
Sam recommends copying days of Discord chat history into ChatGPT and prompting it to list recurring pain points as a fast, free market research technique.
Bhanu and his team built approximately 50 free tools to attract search traffic, each linked back to SiteGPT.
With AI coding tools like Cursor, Bhanu can now create a new free marketing tool in less than 5 minutes by referencing existing tools.
Bhanu filters Ahrefs keyword results to show only those with a keyword difficulty below 10, making them realistic ranking targets for any decent website.
Bhanu sets a minimum search volume of 1,000 monthly searches when selecting keywords to target with free tools.
PropGPT averaged 20 downloads per day right after launching on the App Store through influencer marketing.
