"C was developed in the 1970s at Bell Labs. It was originally designed for
and used on the DEC PDP-11—whose operating system, C compiler, and UNIX
application programs were all written in C."
要是C compiler都是用C写的，那些compiler的原码使用什么编译的？上文的C
copmiler是通常我们说的compiler, 还是其他什么东西？

是不是已经有一个OS和compiler,然后基于他们再用C为这个新机器写一个OS和
compipler。

The second part is a urban legend. Ken Thompson merely talked about the
potential in his Turing Award acceptance speech. So stop spreading it
any longer.

Well, reading comprehension for the lose ^_^ Please read the Chinese
version and tell me they mean the same. No wonder there is a term
called Chinese whisper.
Also, the text has no reference. While Wikipedia is a good place
to look up things. Taking text that has no reference as "truth"
is silly.
Bottom line: if you can find the actual reference, I will give you
credit. Regardless, the Chinese version is just too imaginary.

for every new language, you always need some means of bootstrapping to
create a compiler written in its own.

写一个简单的汇编编译器，可以编译一些简单的C代码，
你可以认为是一个简化的C语言，用这个简化的C语言，
可以写出可以编译复杂一点的C语言的编译器，层层
递进上去。几个版本之后最初的汇编编译器永远用不上了。
以后所有的其他语言也不再需要。

模模糊糊明白了一点。
谢谢大家。
半路出家就是不好。
