This is so pervasive. Even in the mainstream economy where we see universities marketing courses that might seem to lead to employment but in fact are very niche with little chance of leading to a job in that specialism.

I've been looking for piano tuition recently and it's refreshing to see marketing along the lines of how much enjoyment you'll get, with potential to entertain your friends at parties.

I have not. Probably because they simply aren't a significant part of tech or startup culture.

Kids will also easily believe that is cryptocurrencies.

The beautiful cryptography is completely shadowed by speculation.

Care to point out where I made any universal claims about startup culture?

For the record, I agree with you.

Amount of wannapreneurs loosing money on scams, amounts of young adults exploited to work for below market rates for years, amount of scammers hiding under "startup" banner getting money from VCs or small investors are not "one Deepak using quantum healing".

I must not be understanding what you mean. The field of quantum healing is entirely corrupt. There is no such thing, it's all bunk. Do you mean that quantum physics isn't corrupt? Because I doubt anybody thinks that.
