> Unless of course if this isn't about age or sex. I'm female and not getting any younger by the way. But I still don't buy the bull others try to sell.

You're rebutting a straw man.

> No startup is a sure thing. Younger people are less risk averse.

Again, a moot point. If an employee is applying to work for a startup, they're acknowledging the risk. The risk, by the way, is negligible for employees.

> It's not that a company wants people who will take risks it's that older people want more of a sure thing. They walk in and expect a salary which matches their years of experience, while most places hiring have no use for their experience.

This is a contrived example. Furthermore, it doesn't make sense. By a "sure thing" do you mean salary vs. equity? I can assure you most young engineers also value salary.

> Their experience would add no value to their business, and so hiring a younger person who does not demand such a high salary is a better option.

What are you basing this on? It reads like a caricature.

> Clearly if they believe that hiring older people is such a good move they should be able to make a lot of money.

I already addressed this. If you're intent on repeating your original claim, we'll just have to agree to disagree.
