alt Hacker News"extra steps" meaning wearable dehumidifier. Are there other wearable dehumidifiers to produce drinking water? I don't think so.
A reductive assessment (to a specific feature) of a novel idea, does not make it less interesting.

You can wear silica gel since about 1918 - only needs some heat to get the water out and cold to condense it.
Then again, why would you want to wear your dehumidifier (ok ok water harvester)? Is it for excursions into damp areas, so that you can then return to your dry home to extract water?
Then, I believe everything in this video still applies.
Evaporation cools things, that's why we sweat. Condensation heats things. Sure, a wearable dehumidifier may be novel, but does it sound like a good idea to wear a dehumidifier in conditions where you might want to drink the water from one?
