somewhat off topic - it seems like there is a bubble in biotech. Something like 70% of the companies in the nasdaq biotech index have no earnings (losing money!) yet the index is up ~5x in the past few years. echoes of 2001 tech bubble and 2007 real estate bubble.

it does get irritating to hear about "uber as a bubble." Consider how much cash is flowing through uber right now, it is going to become/remain a massive business.
