Ostensibly there won't be any carpenters to hire because they've all been bankrupted by automated contractor services. This seems like a pretty big change to me.

But how does that change the calculation in the grandposter's reply? You can still do it yourself if you want, or you can hire the automated contractor if you don't have the time or effort.

Clearly it doesn't, but why should I care about, much less prioritize discussing, an individual's DIY proclivities when a potentially much more potent issue is available?
