Hot take: We need to rethink how we build distributed systems (read: web apps). The old three tier model of client–app server-database needs to go. For basic use cases it works well enough, but as soon as you introduce complex transaction logic, or high load, it breaks.

Can we replace SQL with functional programming? We take it as a given that relational languages are used to query databases, but there’s no reason we couldn’t use a language based on the lambda calculus!

it’s interesting that you could basically emulate type classes with explicit dictionary passing and row typing. i guess you could also implement monad transformers like this?

You’re absolutely right — you are Pagliacci. It would certainly be difficult for you to attend your own performance! I should not have given such paradoxical advice, and I apologize deeply for the error. There is no excuse for my failure.

a lot of communist theory is flawed because it rests on the assumption that wealth is a common good that just exists, and that "capitalists" are simply rent-seekers who extract value from it. however, in the digital world, this is much closer to the truth
