I had a similar thought, although I do think the article is somewhat useful - I haven't come across many other people supporting the view that efficient and practical startups are a better investment and create higher quality and more useful tech than unicorns.

I do strongly wish the article had more data. Note that the article is labeled as an 'Idea' on the website. See https://restofworld.org/series/ideas/ . I don't think that label should prevent data from being included, though.
