> It's a horrible programming model, though. We should be glad this is not how most languages work.
This is not only about languages, but also environments. The argument Kay makes is that in order to make very large complex systems that are resilient, you need something like this kind of message passing. And indeed, this is how the Internet works too
It's all made possible because of the protocol which is a kind of message passing. If a node somewhere on the Internet doesn't receive a packet for whatever reason, the whole network doesn't come crashing down.
