That’s the thing, I have never seen detailed costs of what people are spending their money on. I know that for Claude there’s a $200 monthly subscription through which assigned credits one burns pretty fast, at which point (and I may be wrong on this, because I’ve never used the thing) one can run extra code on a “pay as you use it” basis? Again, I might be wrong on this.

I’ve also seen it mentioned a lot of people having 2, 3 or even more subscriptions, which I’m pretty sure that can easily go South when it comes to costs.

But, again, and the most important point, I’ve never seen a detailed post on what people spend on this AI thing on a monthly basis (let’s say).

Productivity is literally a statement of the relationship between the result and the cost, presumably you found that out after reading the reply and that is why you switched from "productivity" to "results" in your reply.
