DRAM spot prices are something like what they were 4 years ago. Having RAM for cheap is nice. But it doesn't cost an extraordinary amount. I recently needed some RAM and was able to pick up 16x32 DDR4 for $1600. That's about twice as expensive as it used to be but $1600 is pretty cheap for 512 GiB of RAM.

A 16 GiB M4 Mac Mini is $400 right now. That covers any essential use-case which means this is mostly hitting hobbyists or niche users.
