History provides lessons, for example when came in my first position at the Passive Fire Protection firm I eventually ended up running there was an office staff of twelve people.
I was just a part time salesman at first in 1998 and asked if I might bring in my own spare computer from home to link in to the business center intra-net/internet system. My bosses had no idea what I was talking about but since it was not going to cost them anything said it was fine.
The first thing I did was design a web site and get it on line, I switched for cold calling to e-mail and made an ISO file presentation, I could burn down on to disc as and when needed to send presentations to interested clients.
All the Bosses noticed was that the costs were going down and the work was going up. When our Book keeper left I put in a sage accounting and pay roll system, and increased my hours to full time. By 2001 I was the office manager and we had a staff of four, the annual turn over had tripled and the wage bill was down by two thirds.
This is the point where things got scary we had two partners who had founded the firm, one was a site manager the other was the estimator, the estimator began teaching me his job so I could cover for him during his vacation time, for fun I wrote a simple Excel programmed that could do 90% of his job and cut him down from four visits per client to one for measuring. He was happy enough and so was I, however when the other director saw this, decided to dissolve the partnership and hired an assistant to do the measuring, with me taking over as estimator using my spread sheet programmer.
He went from twelve office staff, and six on site subcontractors to me, a wages clerk and a shared secretary in the office, one director and four teams of four employee on site workers, in lo-jack monitored vans with built in cherry pickers.
Annual turn over had gone from £2.5K to over £1m in five years, simply because I brought in a computer and a few simple programs.
Now imagine today what a modern computer with built in AI can do, without even needing a semi competent arse like me, who had only bought his first computer (an The Amstrad PC1640 HD it did not even have Windows 3.1 it ran the gem desktop operating system and had a 20 megabyte HD that weighed over three pounds ) second hand four years before to use as a word processor. I still have that old dinosaur of a comp today, my wife's phone has over 100 times the computing power and takes up about an 16th of the space.
The computer I brought in to work was not much better, as I recall it ran windows 8 and microsoft office 2000. The boss upgraded me to a slightly better one in 2001 as I recall and again in 2007, but by that time I had had to back to part time working after my wife had her accident. I left completely in 2009, after arranging a merger with an Intumescent Paint manufacturer who wanted to go into passive fire protection and fire stopping and so cut out the middle man.
In short the future with AI in charge scare the shit out of me, especially now they can write music and scripts just on a prompt.
