You completely miss the reason it's grown, and complain through repeated ignorance.
It's grown because it has proven itself, tends to outperform public equity, and provides asset diversification.
It would be dumb for any asset manager to ignore the evidence. I'd certainly fire any asset manager that trades on voodoo while ignoring such signal.
As to working in the industry, you should check my comment history. I've done modeling and fundamental algorithms for a huge range of industries, including new pricing algorithms I developed for investment houses. I have a PhD in math, degrees and grad work on CS and physics, taught graduate mathematical econ at a top 50 univ, and have done significant work and consulting for finance places. So I sorta do know about this.
As to your implication that you do work in this industry, you clearly don't. Just checking your comment history though shows you doing this level of uninformed commenting on topics and people correcting you just like here, going back a far as I checked.
So no, you have no idea about the industry any deeper than someone who read a blog post.

OMG! Commented on in podcasts? Now I believe. For complaining that others can be unsophisticated, you cite this drivel as evidence, against the peer reviewed, track record researchers I posted above?
It figures. Keep cherry picking siloed low information sources to bolster your beliefs. I'll take widely sourced, properly done analysis.
Go ahead and post more. This has more than run it's course
