(SmallTalk legacy cont:) It gave us message passing and late binding, which form the logical backbone of the entire Internet. That idea developed in many places, yes, but SmallTalk was a nexus for it.

The fact the web sites and browsers can be updated independently of each other? that you can visit web sites that didn’t even •exist• when you downloaded your browser? That’s sender-receiver decoupling at work: the Internet is built on messages, and senders and receivers can change independently as long as the message protocol stays intact.

In a far-removed but very real sense, that’s part of SmallTalk’s legacy too!
