“Serious work” doesn’t have to involve big templates of Kontakt libraries. Just because your work involves big templates doesn’t make it more ‘serious’ than someone else’s. 16 gb of unified ram on an m1 chip is plenty for loads of people making a serious living making music. Yes, if it exceeds 16gb it will page it to ssd, but until then it is so much quicker than traditional ram. Even when it does page, the reduction in speed isn’t as bad as you might think.
