I don't see how lockless concurrency is related to writing less code. OTOH I do see how proper use of SQL, which you so hastily left behind, is directly related and beneficial.

Form your post it seems like you're not so much interested in "less code" type of things regardless of their age, and more interested in new things for the sake of their newness, and in "moving on" away from the old things, whatever they are.

Don't get carried away with that.
