I was being hyperbolic, but you see it with companies like Google, Amazon.
Stripe is a good example. You probably haven't heard of it, but it sells software that handles customer payments. When I were a lad everyone wrote their own payment process systems. However, because processing customer payments is largely the same for all systems it makes sense for one company to do it right and then sell a system to everyone else. It is not practical for everyone to reinvent the wheel. Because Stripe can spread its development cost across thousands of systems it can afford to spend huge amounts on development, huge amounts on getting it right. It then becomes very difficult for any new startup software organisation to develop a new product to compete. If someone employs you as a programmer they wonder why you can't develop are the features Stripe offers, in a few months, they don't appreciate the massive amount of programmer time Stripe invested in getting where it is. So, software has a very strong monopolistic tendency.
Even if at the moment there are a few companies competing, if one fails it isn't possible for a new one to take its place. The number of competing companies has a tendency to decrease.
It will probably be worse with AI. This is an existential threat. However, our politicians don't talk about it. They are busy talking about migrants in boats, early release from prison, or getting us involved in some foreign war. The UK political system is worse than most countries for distracting the population with trivia.
