In the last 10 years Silicon Valley and startups in general have attracted a mush of people who bring little or no value to the table. I'm not talking about business/product types or MBAs that might at least have some experience and maybe some contacts and financial know-how. No, its the kind of people who for no other reason are thrilled by the celebrity-esque world of high-flying startups that might come with free lunch/dinner/beer, parties, and items found in The Social Network.
People should learn some product and marketing skills at larger, non-startup companies first before taking sweat equity or low/no pay at a startup. Also make contacts at meetups and learn the finance side of things. THEN you will have less of a problem "Getting into the tech scene", skills in hand.
