The article brings a valid point. If you're a wanna-be entrepreneur and all you have an idea, that's not nearly enough.
If the only thing you - as a technical person - are bringing to the founders table is programming skills, then you're at the wrong table. Get yo bitch ass over to the 'low digit employee number queue'.
You might be one of the first employees, but you're not co-founder material. Technical people who only bring coding skills are just as worthless as non-technical people who only bring an idea.
