I have been looking for other ways to invest than putting my money in the stock market. Luckily today there are new ways to invest that were not available 20 years ago. I think way too many stocks' prices are disconnected from their actual value (or even future value). To some extent, the stock market has become a legal gambling platform. Also the market is biased towards the professional traders and it's not serving the average person that worked hard for their small money and it's way too easy to loose a big chunk of your $$$.
Also, i would have loved to see the article talk about the increase in private investments (ie VCs and Angels) Elon Musk said it himself: he tried his hardest to keep Tesla private but he just couldn't, he had to let go and IPO. He swore to not make that mistake again with SpaceX (more here: https://www.quora.com/Why-did-Elon-Musk-make-Tesla-go-IPO-bu...)
