'Jeff, what does Day 2 look like?' 'Day 2 is stasis. Followed by irrelevance. Followed by excruciating, painful decline. Followed by death. And that is why it is always Day 1.' To be sure, this kind of decline would happen in extreme slow motion. An established company might harvest Day 2 for decades, but the final result would still come.

Science is the art of asking the right questions.

A LISP programmer knows the value of everything, but the cost of nothing.

I don't know anyone who needs a subpar version of themselves.

No arts； no letters； no society； and which is worst of all， continual fear and danger of violent death； and the life of man， solitary， poor， nasty， brutish， and short.

这个世界充满了征兆和奇迹，但我们每天走过却视而不见。

Love is not a victory march, it's a cold and it's a broken hallelujah.
