After all, Gold reached a glorious bubble of inflation-adjusted $2200+ / ounce in 1970s, and has fallen since then. (yes, even with today's inflated prices, Gold is no where near its inflation-adjusted high).
Lets take a more reasonable graph of Gold, ehh? Something longer term... and see what happens to your trend.

Gold's trend is downward compared to the majority of the market. Each valley is lower, and each peak is lower than the last (with exception of stagflation period in the 70s)

VIX for the S&P 500 is 13.58, while Gold VIX is 13.13. Stocks are both holding their buying power as well as Gold, and still offering better returns right now.
Gold's "stability" is a myth. It is no more stable than any other investment. Bonds offer a conservative, stable investment platform. Gold does not.
Stocks as investment:

And of course, ycombinator. You know... the angel fund / venture capitalist firm that runs this website? We're all here because of investors investing into technology. They do so because they believe they can ultimately make money with technology investments. At least, more so than Gold, Real Estate, or even Stocks.
You might be able to make a little bit of money, but unless the global economy collapses entirely, I doubt we'll see another major increase. Gold actually has gone down in value before, so it could easily happen again again.
Relative to what? The USD?

Real estate?

Gold is an asset that holds its purchasing power pretty well. It is what it is. It is not however a "piss poor" investment.
