1
00:00:03,390 --> 00:00:04,870
Software is all around us

2
00:00:06,010 --> 00:00:07,870
and sometimes inside us.

3
00:00:09,720 --> 00:00:10,480
But what happens

4
00:00:10,680 --> 00:00:11,730
when the tools we use

5
00:00:11,920 --> 00:00:13,530
are obeying someone else?

6
00:00:14,640 --> 00:00:15,690
A tool you control

7
00:00:15,860 --> 00:00:17,860
serves your interests,

8
00:00:18,260 --> 00:00:20,310
but if someone else controls it,

9
00:00:20,840 --> 00:00:22,460
they serve their own.

10
00:00:23,050 --> 00:00:24,560
When you can examine tools

11
00:00:24,790 --> 00:00:25,890
to see how they work,

12
00:00:26,060 --> 00:00:27,420
you're able to learn about them,

13
00:00:28,110 --> 00:00:29,180
even modify them

14
00:00:29,350 --> 00:00:31,250
to work differently or better.

15
00:00:32,890 --> 00:00:34,310
When you can share a tool

16
00:00:34,500 --> 00:00:35,590
and its changes,

17
00:00:35,780 --> 00:00:37,200
you help others and, in turn,

18
00:00:37,380 --> 00:00:38,460
they help you.

19
00:00:40,100 --> 00:00:40,850
In fact,

20
00:00:41,020 --> 00:00:44,050
this is how early computing developed.

21
00:00:44,210 --> 00:00:46,010
Everyone could see a program's code

22
00:00:46,180 --> 00:00:47,760
and people shared their work freely

23
00:00:47,950 --> 00:00:49,960
to drive its growth.

24
00:00:51,650 --> 00:00:55,040
Every user was a potential author.

25
00:00:56,970 --> 00:00:58,070
But when companies began

26
00:00:58,240 --> 00:01:00,460
to lock source code away,

27
00:01:00,720 --> 00:01:03,550
it stopped being possible to participate

28
00:01:03,730 --> 00:01:07,290
or even to know what the code was doing.

29
00:01:09,270 --> 00:01:10,020
In response,

30
00:01:10,340 --> 00:01:12,290
hackers formed the GNU project,

31
00:01:12,690 --> 00:01:14,070
to create a computer system

32
00:01:14,250 --> 00:01:15,360
designed to respect

33
00:01:15,550 --> 00:01:17,730
the autonomy of users.

34
00:01:18,630 --> 00:01:20,610
They adopted a copyleft maneuver

35
00:01:20,910 --> 00:01:21,520
and built it into

36
00:01:21,720 --> 00:01:23,590
the GNU General Public License,

37
00:01:23,780 --> 00:01:24,550
a legal structure

38
00:01:24,720 --> 00:01:26,630
that preserves user rights.

39
00:01:27,910 --> 00:01:29,270
In ten short years,

40
00:01:29,450 --> 00:01:30,530
the free software movement

41
00:01:30,700 --> 00:01:32,920
had produced the GNU/Linux system.

42
00:01:33,230 --> 00:01:34,420
Computing that nobody could own,

43
00:01:34,590 --> 00:01:36,310
but anyone could use.

44
00:01:38,540 --> 00:01:40,660
Today it's keeping planes in the air,

45
00:01:41,440 --> 00:01:43,920
stocks trading

46
00:01:45,240 --> 00:01:48,170
and the global Internet running.

47
00:01:50,510 --> 00:01:52,120
We all encounter free software

48
00:01:52,320 --> 00:01:53,760
in invisible ways.

49
00:01:54,140 --> 00:01:55,170
But software freedom

50
00:01:55,350 --> 00:01:56,870
was designed for people.

51
00:01:57,400 --> 00:01:58,290
It's about what shape

52
00:01:58,490 --> 00:01:59,860
the technology we inhabit

53
00:02:00,060 --> 00:02:00,880
will take,

54
00:02:01,120 --> 00:02:02,160
and what kind of society

55
00:02:02,340 --> 00:02:04,620
we use our digital powers to build.

56
00:02:14,650 --> 00:02:17,630
We've still got work to do.
