I’ve had to do some sales in my life. Not much, but sometimes you have to convince someone that your services are worth doing. And if you talk to people, a lot of people are in sales. Sales is of course one of the most fundamental parts of business - in the end, no business can continue without some moolah. No business can even start without some level of sales. Business from a certain perspective is just sales.
Sales is though a very particular and refined social skill. It is the skill of convincing someone of a dream, of convincing someone to drop their natural cyniscism and adopt your perspective. And as such, it is particularly tied to social structures. There are some ideas of how to automate this skill - to some extent, recommendation and placement algorithms do a large proportion of saleslike work - but for larger clients and higher prices, salespeople will still probably be necessary for a while longer. They will probably be one of the last professions to be entirely automated since their skill is fundamentally tied to humans, not to information or to physical laws, and thus human society will probably still leave a gap for them. Thus eventually, everyone will have to be in sales, as the last remaining profession in the long run, besides AI prompter. Thus in the year 2084, all other professions will have long been subsumed into sales, and it’ll be the main focus of most non-technical institutes and organizations. In the end, the salesman will be king.
