We have a lot of artists who ask for MPBs with 64GB RAM, and when I ask for work samples, there's not even enough memory pressure to swap on their 16GBs. When I ask why they need it, and they always give some variation of "it renders too slowly".

It's not my job to help people pick out computers better suited to do the work they were hired for, but I really enjoy seeing the characteristics of and where the bottlenecks are in new generations of hardware.
