That article seems to harp on the fact that it is "not-com bubble", basically that the companies are getting punished because they are not "pure tech/software companies". Quite a way to miss the point, IMO. As if delivering pure software was a sign that the company is worth investing in. Just look at all the cryptocurrency/blockchain startups from about two years ago. Most of them literally didn't have anything else…
Well, this generation of investors, at least. ;) We had much the same thing happening 20 years ago, and I have no doubt that we will again.
