The comments from the HN link from 1 year ago aged so badly. They were all skeptical that fiber optic control would become popular.
Especially true for SW engineers and other privileged people (politicians are an even better example) who due to their high status and wealth assume that if they got a well paid job, then they must be super smart and right at any other topics or areas, and then end up shocked that their viewpoint gets demolished by the masses or by the end results down the line.
In a way it's like how democracy works: it doesn't matter what is right and what is wrong, the opinion that ends up denominating is what the the masses perceive as being right.
