Reply to comment by nullrecord in ELI5: Why do we only use 1 and 0 for binary? Could we create a trinary system introducing an extra '2'? by No-Mammoth-1638

That's a good point, lots of transceivers do encode/decode signals with multiple levels. I was only thinking about the processing and storage of data. Even a qam-64 symbol needs to be converted to binary to do anything useful with it.

Sure, but as someone wrote in the other comment, even SSD stores multiple voltages per cell to increase storage capacity.
