I guess there will be more demand but I disagree that demand is infinite or almost infinite, there is finite amount of humans and companies and these have finite demand as well

imgien for example there is software company making antivirus software, its enough if there are several companies like that, ppl dont need 1000s different antivir software several decent one is enough, there wont be really much bigger demand for more

when 1 programmer will be needed to do work of 10, that antivir company wont need the rest, yes they can speed up the work and improvement by keeping 1 or 2 aditional ppl- that would already mean company is about 20x more productive, there is only so much work that should or could be done on your product in small timeframe

some of those who will not be needed in their companies could go to some other projects, but their amount will be finite as well
