I've listened to only 2/3 of it, but: he promotes Crystal+Lucky (crystal is compiled) as good replacements for Ruby and Rails. The second part of his talk is about promoting a new variant of open license called PostOpen, which will require commercial users of Post Open software to pay 1% for using, 1.5% for using without sharing modifications. There is a 10% fee for worse offense. All percentages are percentages of revenue. This is partly aimed at large companies that host open source software with few modifications as a service and charge for it. Money goes to PostOpen and possibly conventional Open Source developers.
