The Subscription Service Bubble Is Part Of The Tech Bubble

I wrote not too long ago that there is obviously a tech bubble and pointed to subscription companies as proof. Economist Matthew Martin posted recently on twitter that these subscription companies are not "tech startups", because subscription companies "go way back and there has been essentially no innovation". On the one hand, I'm happy to say "fine they are just startups and what I mean is there is a startup bubble". I don't really care about quibbling over the definition of a tech company, and my point is that there is bubbly corner of the economy filled with startups and many of them look alike, whatever you want to call them. On the other hand, no, I am right.
