The problem with systems design is that it's all so complex. Multitasking has become an excuse to run everything as some absurd daemon. Badly designed hardware has to be papered over with undocumented binary drivers. Everything is optimised for throughput benchmarks, so we get warm ups and unpredictable pauses visible to the user. And it's all full of security holes.

The plain truth of the matter is that none of these things are due to a lack of special language support. It's that the whole system is too complex, and the complexity isn't even quarantined in such a way as to be harmless. We need to be able to start over (something the author acknowledges). We can't do this if we build yet another complex system in the belief that we'll get it all right this time round.
