We keep hearing today how machines and robots are replacing human employees at an extremely fast rate, but make no mistake: THIS HAS ALWAYS BEEN THE CASE! A simple look at military history will easily convince you.
Guns and bombs gradually replaced bravery and physical battles, but you will never hear anyone (especially imperialistic governments) complaining about that. HECK, even robots ended up using other machines.
So, I don't see why someone who takes alarm clocks for granted for example, should even complain about a robot replacing him at the office. Did you even know that being a "human alarm clock" used to be a legit profession before these little noisy things became a trend?
The Menu of the Day
Now that you're ready to accept the fact that mankind's astonishing technological achievements have replaced (and will keep replacing) many jobs that humans once used to do, let me introduce you to a long-forgotten profession; this of the "man alarm clock."
Wait a minute...I GOT IT ALL WRONG! What I meant to show was this hard-working gentleman right here...
This job was extraordinarily popular in the UK, where it started at the dawn of the Industrial Revolution and lasted until the early days of the 20th century.
Did "Human Alarms" Need Batteries to Work?
Of course, a "human alarm," also known as a KNOCKER-UP, needed no batteries or electricity to work; just a full English breakfast and a cup of tea before work, and maybe a couple of beers in the local pub after duty.
So, how exactly did the whole thing work you wonder? The "man alarm clock" used a super-long stick made of bamboo, which helped him to knock even the highest windows on the upper floors. He wouldn't stop to knock until the customer opened his/her window to tell him to Shut the F$$$ Up! After all, old habits die hard...
Did He Make a Lot of Money?
Each client had to pay several pennies a week in order to wake up on time, which meant big business for the "human alarm clock," especially if he was really popular in the neighborhood and had many satisfied customers.
The specific job became mostly popular in London and Birmingham, where it was mainly "executed" by older retired males and police officers on their morning patrols, in order to make some extra cash...Well, before they discover that as a cop there are way more profitable ways to make some "extra cash."
