I think we may be discussing different things. When I talk about the DMCA machine, I mean the cottage industry of firms that make it their job to check the internet for infringement and file the appropriate claims. I'm not referring to Google's AI.

My point was that those firms currently cater to large creators/the cost only makes sense for firms with lots of IP. BUT, if it was cheaper/more accessible (and profitable to litigate in this area) then more small creators can do it, and the problem becomes more acute for large content hosters.

Yes but as i said two posts ago, those firms are not famous for their competence, they mostly carpet bomb everything.
