Is it just me or even anyone else who's noticing that there are too many PM courses. And the courses are portraying as tho every Tom, Dick and Harry can become a PM. Linkedin is flooded with teardowns. What y'all think ?

Every Tom, Dick, and Harry can become a PM. Not a good one, but sure, a PM. Isn’t that what the marketing strategies of these courses tell you anyway? They don’t really state how good you’re going to be. Besides, most people don’t really purchase them for the course per se, you can learn it for free online. They mostly purchase it for the placement guidance/assurance.

All good courses have a gate at the start and don't allow everyone to join

Yes it's true. We need some good gatekeeping.
