When we see someone working very hard, say a lumberjack cutting down trees with a hand saw or an axe, we’d laugh and think that the man is just rather doing his body-building. Any chainsaw and esp. tree felling machines are so much more effective.
A 100 years ago this was still considered serious, important and definitely hard work.
When we see someone working out maths calculations in his head or on paper, we’ll laugh and think this must be for school. Any cheap calculator or even computer is so much faster and always accurate.
50 years ago there were no calculators or computers and this person was a valued, hard working expert.
At their times people were hard workers doing these things. Now all this work is still done, but there is no hard work involved any more.
It goes on like this… most things that meant “hard working” to us are done by machines and computers. Are we “lazy” because of this? Is being “lazy” bad or good from this perspective?
For sure, what is presently considered “hard work”, will become ridiculous tomorrow.
