For example, it appears that the "barrier of entry" for repairs was lowered, and I could pick many examples to try and demonstrate that, but just from a personal anecdote: I usually don't work on my car unless it's something simple that requires a solution I can instantly think of, but just the other day I had my engine temperature light pop up at a rather inconvenient time and place, so instead of calling assistance, towing the car to a mechanic, and having them work on it for I don't know how much time and money, I took a look at the usual suspects (radiator, hoses, coolant tank, etc.), pointed the camera at them, and started talking to ChatGPT which instructed me on how to troubleshoot, find the defective part, buy a new one (which I did by phone and got it delivered to me), and replace it on-site. And now I feel more confident in doing just that for bigger problems from now on, which, granted, is probably a bad idea, but I digress.

The Marxian perspective says the repair I did on my car is an effort that will never express itself as value because I do not intend on selling my car as a commodity in a market, so it's not labor per se. It literally replaced the living labor, the value-producing activity of a mechanic, and added nothing back in its place. So indirectly, that also contributes to the reduction in overall new value production, which can only be created through living labor. But the consequences of that will not happen instantly, because the demand will lower in one sector (e.g. mechanic shops) and increase in another (e.g. I spend the money I saved in a diner or something). But there might not be enough room to absorb the displaced workers in another sector, and even if there is, the wages will tend to be lower for the inexperienced newcomer (say, if the mechanic chooses to work in a kitchen now).

That just seems like a terrible spiral. Think about it: this time, I chose to do the fix myself because of time constraints, but what if I were the one getting caught up in one of these traps? What if I had been laid off or had been displaced to a lower-wage position and couldn't really afford to bring my car to a mechanic? Then it's EVEN MORE pressure to not opt to use services and try an AI-assisted fix.

Anyway, I might be way off here, but it's an interesting topic.
