I came across this question on Computer Science Stack Exchange: Why did finite-state controller with datapath win?
It's a historical question that was well received. In the same spirit, I asked this question on Electrical Engineering Stack Exchange: What are the factors that led to the digital revolution?
The question is about why digital electronics surpassed analog in communications and processing. It's hard to see why this question is opinion based. In fact, it looks very similar to the one asked on Computer Science Stack Exchange, since it is about why one technology/methodology got preferred over the other. This Q&A was partially inspired by the documentary from IEEE Information Society titled The bit player that I watched.
So why was it closed, and what is opinion based about it? I'd like to gain a better understanding so I can avoid it in the future.
