I haven't tracked it recently, but when I've pulled up the metrics I've generally seen about 25% token saving (sometimes higher circa 40%, depending on type of use). I've bought a max Claude plan recently, as I couldn't make enough savings to stay on the Pro plan. Perhaps most importantly, I've not seen any conflict or degradation after installing the plugins, which I've done on both Windows and Linux. Recommended, so far.
I find something similar happening as I transition to spec driven development - whilst the agents do the work I used to do, I spend a hell of a lot more time thinking about what I want the outcome to be, rather than hacking around the limitations of frameworks I know, avoiding tech I don’t. It’s freeing actually.
Include clear payment terms and penalty interest. For me, this looks like 30 payment window, reminders fortnightly there after, and a money claim lodged in the small claims court at 90 days. You’ll almost certainly get your money ahead of court appearance (assuming they haven’t gone bankrupt).
I’m seriously not astroturfing, point is serious. Most people here would not be able to tell the difference between good human and good AI generated writing anymore in a blind test, especially a blend of both. So if the reader often can’t tell, why is the source of a well written, interesting piece of writing more important, than the effect of the content itself? I don’t feel the OP made a good argument imho.
