Fair. I read the comment as, more or less, "the typical laptop has so much RAM these days that putting ~/.cache on tmpfs would be a reasonable default" or something like that. But I guess it could -- and should -- be read as, "if you spend a bunch extra on RAM, you can get laptops with so much RAM these days that you can consider putting ~/.cache on tmpfs", which is reasonable enough.
