Unless you are actively using all that RAM simultaneously (instead of simply leaving a few applications open and switching between them) modern SSDs and zram significantly reduce the need for loads of main memory imho; it just isn't an issue if the web browser uses xx GB over time or the IDE requires a few gigs or a VM here and there needs a couple gigs because almost all of that is going to get paged out when not used actively, and once you get back to it, no big deal to have it paged in at a few GB/s. Laptops with 16 GB are common, 32 or 64 a lot less so. And laptopts with fixed memory are going to be more power efficient and somewhat higher performance (usually).
