I have read the whitepaper but I was told by many that was a typo. Should be 1,000,000 and not 100,000,000. Also, see this blog post written after the whitepaper (3rd to last paragraph). https://blog.genesis.vision/becoming-a-gv-manager-729c2d75d9fa

But ya I agree they would have to be transparent in changing the max amount of management funds to accommodate demands. 

also, lets say the medium term marketcap target is 4 billion, you would need 4000 top level managers to get us to that point. (plus or minus given other factors that affect price).
