While I agree on the premise – (written*) lawyer activity being reduced to putting signatures under things – I’m not so sure the gilded part is how it’ll actually play out in practice.
It might also become a race to the bottom, since you can’t deliver on quality better than others anymore, you’ll have to put effort towards quantity. That could mean firms might pressure lawyers to sign as much as possible in a given time, while they’re still personally at risk/responsible for the documents they put out. That means either very hectic reading, and missing details, or no reading at all.
*And like socializer said, the written documents are only one part of the job.
