Ask HN: What will be the next “big things” in computer hardware engineering?

Hi,

i just read an article about a new storage method, kind of a persistent storage based on DRAM technology. I asked myself, what will be the next big steps in hardware engineering? I'm not talking about DDR8 Ram or 7nm Processors. I think about steps like HDD to SSD, which made all computers faster and more silent. Fundamental new hardware designs which will make a computer better.

What do you think?
