未来可期，还可以想象

以前总是很乐观，这个世界总会变得越来越好，现在有一点悲观，似乎向着一个我不喜欢的方向越滑越远，争吵，互怼，新冠疫情把大同世界击个粉碎，地球村到处树起藩篱，到处是有形的和无形的高墙。

作为一个误学理工的文学青年，少年时读了许多中国的文字，唐诗宋词的美深深印在脑海中。例如:

---

登高 - 杜甫

风急天高猿啸哀， 渚清沙白鸟飞回

无边落木萧萧下， 不尽长江滚滚来

万里悲秋常作客，百年多病独登台

艰难苦恨繁霜鬓， 潦倒新停浊酒杯

---

江城子·乙卯正月二十日夜记梦 - 苏轼

十年生死两茫茫，不思量，自难忘。千里孤坟，无处话凄凉。纵使相逢应不识，尘满面，鬓如霜。

夜来幽梦忽还乡，小轩窗，正梳妆。相顾无言，惟有泪千行。料得年年肠断处，明月夜，短松冈。

后来又学了很多西方世界的科技知识，放弃了自己的文学梦，转行做了程序员，开放源码和自由软件是我深以为然，由程序员为这个世界贡献出的价值观:

---

Free software is a matter of liberty, not price. To understand the concept, you should think of “free” as in “free speech”, not as in “free beer”.

More precisely, free software means users of a program have the four essential freedoms:

• The freedom to run the program as you wish, for any purpose (freedom 0).

• The freedom to study how the program works, and change it so it does your computing as you wish (freedom 1). Access to the source code is a precondition for this.

• The freedom to redistribute copies so you can help others (freedom 2).

• The freedom to distribute copies of your modified versions to others (freedom 3). By doing this you can give the whole community a chance to benefit from your changes. Access to the source code is a precondition for this.

Developments in technology and network use have made these freedoms even more important now than they were in 1983.

东方的古老文明和西方的现代科技并不冲突，资本主义和社会主义都各自有很多问题，相向而行，取长补短，未来才会更美好。瘟疫来临，清楚地照见人间许多的黑暗。

列侬写过一首歌，歌名是想象，想象一个大同世界，没有国家，没有宗教，没有杀戮，没有饥饿，也许这就是共产主义吧。虽然对现在这个世界很失望，我依然希望，想象会有这么未来会有这么一个世界。

Imagine

Imagine there's no heaven

It's easy if you try

No hell below us

Above us only sky

Imagine all the people living for today

Imagine there's no countries

It isn't hard to do

Nothing to kill or die for

And no religion too

Imagine all the people living life in peace, you

You may say I'm a dreamer

But I'm not the only one

I hope some day you'll join us

And the world will be as one

Imagine no possessions

I wonder if you can

No need for greed or hunger

A brotherhood of man

Imagine all the people sharing all the world, you

You may say I'm a dreamer

But I'm not the only one

I hope some day you'll join us

And the world will be as one
