If your goal is to get rich, sure. But going with the herd isn't necessarily unsafe. The goal of "getting rich" is generally incongruous with passive investing either way.

The risk/reward profile of active investing and index fund investing are completely different, so that will be more than a decision of upside you want to pursue.

It remains to be seen how risky passive index investing is now that so much money is in it.

You haven't talked to many people then. There are plenty of people who've built wealth via index funds.

I've built my wealth significantly with index funds. "Get rich?" No, but that's not my goal because getting rich requires a ton more risk, usually leverage, and tons of work.
