It has become clear to me that the stagnation of productivity increase since ~2000, is directly caused by IT and is a consequence of it.
Generally the goal of IT,AI etc is not increased efficiency, or overall productivity, but just to push the wealth up the food chain and to concentrate it.
My wife's company recently rolled out (so called) AI routing software for the trucks, letting them fire the dispatchers. Supposedly this will be faster as supposedly the software knows how long every road takes, and where all the hold-ups are.
Except it doesn't. The drivers and dispatchers already know how fast the roads are, and since ~1970, all drivers immediately know about any road issues, as they all were listening to the same radio telephone channel and they tell each other what and where.
The AI however only knows any of this somewhat late, after a bunch of traffic has been slowed down. It never knows the root cause, because it understands nothing, and it can't predict what will happen for the same reason.
So they got rid of two (low paid) people by using "AI". Productivity is down >10% - that's 10% of 50 drivers, and 50 trucks, and the processing plant they feed. They have lost 12 drivers (who can get jobs elsewhere), and can't replace them, and now have trucks idle (just the finance cost of a truck exceeds minimum wage). Fuel burn has increased not decreased due to more idling in traffic. The cost of the software certainly exceeds the two salaries they "saved". And they can't go back as they ripped out the voice RT's and put in tablets - which themselves have already caused a couple of accidents, and which are going to result in a decent fine, as it is illegal to use them when driving.
The best part is that the competitor who is eating their lunch, has two people in every truck - a driver and a spotter, not just one driver.
