The saying gose:"most ancient profession in the world", even if it is not so old they tell us, it sure must have choed throuht out time. Many things are much more older then you may think, and the same way ofc around. That is many saying are much younger then you may think. But to the point!
Ofc, we all know that "most ancient profession in the world" is not true! The truth is of cours with a brain you can understand that the first profesion was trade. Why? Because before prostetution there is trade. How much money the sex is gona cost you!!! And rape or just reproduc/procreating is not sex for something else! Just look at animals, today! What do they do? They trade!!! Plant lice trade for security and food with ants. [LEL 8 YEAR OLD KID LOGIC]. My point is that trade is before athleast prostetution. But why did Rudyard Kipling say it?
Lets go down the rabit hole. Ofc, he probebly heard it from some farmer on the farming grounds and piked up. So it was probebly not he who came up with the ide, only the first person to print it on papper. Now what did thoses ancient people know what we did not know? The thing is this! Like Isac newton did not eat a apple, he is just metaforing what Eva and Eve eat from the forbiden fruit of knowlegde. THe same thing is with prstetution, it sounds COOL thus it is more rememberabel, that is it! Isca newton was just self inportant syndrom, because he followed the jews(lel, no at just that people) way: A person is a live only if other people know that he exist.
SO what has prostetution to do with anything? I am not trying to sound disgusting here. But when the robots take over that is the only work left for us humans to do. And it will be rebot dicks inside of your assholes. Because you can not replace the real deal(huamns) with robots, and if robots want to have sex with huamns you need to have the real deal, you can not replace the real deal with something else. So the oldest profesion will be still here, because you can not replace huamsn with something else. If you want to have sex with humans you need humans.
I hope you are looking forward to taking robot dicks in 50 years, time, because that is the only way you will be able to make money !!!
