Roughly 80 years ago many computers used analog logic, for example an amplifier with variable resistors could multiply and divide.
The matrix multiplication seems to be central in Transformer architecture.
I wonder if it would make sense to create a sort of Transformer on a vaguely similar concept?
If you wonder why this question, after all there are still guys who design digital computers with tubes or even mechanical relays, then why not analog Transformers?
