Dating markets are lemon markets. The classical example of a lemon market was the used car market - most people who bought "lemons" (unreliable cars) would exploit information asymmetry and sell them on the used market, and over time the reputation of the used car market deteriorated to the point where it was affecting the value of new cars. The car manufacturers solved the problem by introducing gatekeepers - certified used car programs, that certified that the cars weren't lemons.
So who are the "lemons" on dating markets, which bring down the reputation of dating markets for the rest of the players? People who aren't in an emotionally healthy place to make commitments; people who are "players"; people who are violent; etc. It is our experience dealing with the lemons who stay on the dating market that ruins the reputation of the entire dating market and makes dealing with the market difficult.
So the solution is to introduce a gatekeeper. What does a gatekeeper look like? A clinically trained psychologist-cum-matchmaker (pun not intended) who can certify that the matches you are set up with are people with a track record of dealing honestly (for your personal definition of honest) in the dating market. Don't like your gatekeeper? Pick a different one.
So far as I can tell, healthy dating markets are limited to scale by the need to hire such competent human gatekeepers. If anyone has an idea how to automate the gatekeeping in a humane way - you're sitting on a gold mine.

There are existing heads-up display products targeted at cyclists such as the Everysight Raptor and Garmin Varia Vision. However they aren't practical or comfortable for runners.
Ideally I'd like the smart glasses to have the following features: ANT+ Extended Display profile. 6 hour battery life. Lightweight with even weight distribution (not all on one side). Prescription lens compatible.

The only downside is that when you dispense water it lights up a little sign that says "water is not filtered".
I do this and buy cheap aftermarket filters from Amazon.
As in another comment here about Copenhagen, you cannot swim after hard rain because of how the sewer systems were designed. Seattle is famous for rain, but not the type of rain that will cause a spill over event often.
The county government also tests the water for bacteria and algae and reports the findings on their website and closures are signed at access points.

Also while there is a lot of private ownership of water access, there are 9 city beaches and something called street ends, which are public right of ways if a street ends at water, I swim from these all the time.
