Serious question - why does anyone think PE can be disrupted if techies and techie founders have not been able to disrupt our own broken illiquid equity situation? The only answer can think of is (pessimistically) that the system is broken because it is profitable (to some) to keep it broken for many others. PE wields far more influence Than pre IPO tech equity so I definitely don’t see that being disrupted first.
