i dont think we'll ever saturate the amount of software there is in the world unless we get some sort of scifi superintelligence scenario

Software allows us to build essentially infinite abstractions with infinite room to run. cheaper and better models released to the world means higher competition which drives up the cost for talent

however i think the value of 'hand crafted code' drops to zero unless we convince consumers to purchase software as a status symbol like rolls royces (seems unlikely, unless there is a concentrated marketing effort)
