Yeah. I mean, sometimes RAM getting “wiped” is a “feature”, e.g., you don’t want somebody to be able to pull information from RAM after you shut off your computer… but that’s not really what it’s designed for (and you can recover data from powered off RAM in some lucky cases). It’d be sweet if we could have fast non-volatile memory. Having a computer use 0 power when suspended and not having to worry about hibernating to disk would be sweet! I do kind of wonder about the security RAMifications of that, but I guess it’s not much worse than having a laptop suspended currently.
Wouldn’t it kill your hard drive quickly if every bit in memory was constantly written there - if it was all virtual memory? I think of it like “stuff in my desk” vs “stuff on top of my desk”, and now nobody mixes up the papers on my desk when I walk away.
That’s what RAM is. Following your analogy, you’ll put stuff occasionally inside the desk when you’re done with it, and keep working what’s on your desk. I see persistent ram as like working inside the desk, which is a bit weird to me. Or a desk that just never gets cleaned up.
I don’t understand the point of this. That’s what the hard drive I for. The RAM is meant to be wiped.
RAM is not meant to be wiped. It’s just we haven’t found a way to make it constant, but still as quick as it is now.

That last one is how I see it too. Just never gets cleaned up.
