1
00:00:06,555 --> 00:00:09,173
Mysteries of vernacular:

2
00:00:09,173 --> 00:00:10,816
Robot,

3
00:00:10,816 --> 00:00:12,658
a machine capable of carrying out

4
00:00:12,658 --> 00:00:15,793
a programmable series of actions.

5
00:00:15,793 --> 00:00:18,045
The origin of the word robot

6
00:00:18,045 --> 00:00:20,678
dates back more than 1,000 years

7
00:00:20,678 --> 00:00:23,879
to the era of serfdom in central Europe

8
00:00:23,879 --> 00:00:27,218
when servitude was the currency for rent.

9
00:00:27,218 --> 00:00:28,234
In those days,

10
00:00:28,234 --> 00:00:31,165
the old church Slavonic word rabota

11
00:00:31,165 --> 00:00:34,180
described the forced labor of the people.

12
00:00:34,180 --> 00:00:35,928
A slight adjustment of the spelling,

13
00:00:35,928 --> 00:00:40,845
and rabota became the Czech robota,

14
00:00:40,845 --> 00:00:44,370
which, in addition to defining to toil of the serfs,

15
00:00:44,370 --> 00:00:46,330
was also used figuratively

16
00:00:46,330 --> 00:00:50,310
to describe any kind of hard work or drudgery.

17
00:00:51,095 --> 00:00:55,118
In 1920, Czech writer Karel Capek published

18
00:00:55,118 --> 00:00:59,131
a science fiction play called "R.U.R.",

19
00:00:59,131 --> 00:01:03,250
short for "Rossum's Universal Robots".

20
00:01:03,250 --> 00:01:05,844
The story featured automated machines

21
00:01:05,844 --> 00:01:08,081
with distinctly human features

22
00:01:08,081 --> 00:01:09,746
that, until they revolt,

23
00:01:09,746 --> 00:01:13,089
catered to the whims of the people of Earth.

24
00:01:13,089 --> 00:01:14,852
Capek originally considered

25
00:01:14,852 --> 00:01:18,764
calling these hard-working machines labori

26
00:01:18,764 --> 00:01:21,700
from the Latin word for labor,

27
00:01:21,700 --> 00:01:24,615
but he worried it sounded a bit too scholarly.

28
00:01:24,615 --> 00:01:28,149
He opted, instead, to emphasize their enslaved state

29
00:01:28,149 --> 00:01:30,580
by naming them roboti,

30
00:01:30,580 --> 00:01:32,954
or robot in English.

31
00:01:34,107 --> 00:01:36,924
"R.U.R." was wildly successful,

32
00:01:36,924 --> 00:01:40,910
and when it was translated into English in 1923,

33
00:01:40,910 --> 00:01:44,841
the word robot was enthusiastically embraced.

34
00:01:44,841 --> 00:01:46,936
Though most of today's robots look

35
00:01:46,936 --> 00:01:49,628
quite different than Capek imagined,

36
00:01:49,628 --> 00:01:53,155
they've become just as popular as he predicted.

37
00:01:53,155 --> 00:01:55,426
Unlike in "R.U.R.", though,

38
00:01:55,426 --> 00:01:58,811
our robots haven't risen up against us,

39
00:01:58,811 --> 00:02:01,768
and here's hoping it stays that way!
