Why do SSDs have a more limited number of times data can be written to them, but RAM memory can handle loads of re-writes? (self.explainlikeimfive)

In a similar vein, why can we not use the technology of RAM to prolong the life-cycle of an SSD?

Slightly misleading, the DRAM chips do that themselves so the kernel doesn't have to do that.

Some very early systems did do it at kernel level, but yeah you are correct. Though I'd also consider the dram chips to be part of the computer and DRAM refresh makes up a good part of your phones battery consumption at standby.
