There’s a difference between technical at the leadership positions vs every position.

Nvidia’s CEO is technical. Google’s was technical for a very long time. AMD’s is technical. Amazon’s was for a very long time. Microsoft’s was for a very long time and is again.

I think it’s a bold claim to make that technical people are only capable of designing for technical people. There’s plenty of people who understand how to build products that connect to the consumer and non-technical people don’t have a unique ability to do so.
