I have something on the order of 20m^3 worth of clothes. I'm seriously weirded out by how none of the "fashion tech" companies do anything regarding appropriate outfits for the weather conditions. 50% of my outfit choosing time is spent figuring out whether fleece works for 0C-but-windy, what the right number of layers is for stuffy public transit, breezy outside, and chilly office AC, and whether something is at risk of majorly embarrassing malfunction if I run. I don't need an AI to have taste for me (thanks but I have it we can't all be clueless-and-nerdy...), I need it to have fast, appropriate decision-making in case my original plan falls through because of surprise snowfall.

You're welcome to make a startup based on that idea ;) up here in Canada where we have real seasons I'll find you some great test users!

(Although I've been to the Bay Area and it's not without weather challenges)
