If they didn’t have hype, they wouldn’t be funded and they wouldn’t get off the ground. Hype is now an unfortunate requirement of any successful company.

But the big disadvantage is when the hype will work against you, there are many examples like the No Man Sky game that was a decent game but because of the hype it will be forever remembered on how not to hype the product, in the present the game has the promissed features but very few will take a look at it.

I understand that a company wants good PR, but I think you need to keep it real, like if a dude posts a video of Tesla self driving on some roads instead of Musk sharing it they can not do it or share but put a include the message that you mustk keep your hand on the wheel and pay attention. The reality is that now a Tesla has a non zero chance of driving you into a large object and killing you, when this happens your public image suffers when you promised autopilot but if you instead market this as a drive assistant that collects and learns how to drive and in future will become autopilot then the backlash will not affect you.

I know that in small print and the big TOS this things are very clear but the PR and social media activity of Tesla and Musk contradict those terms.

The balance between making promises and delivering on them is always and difficult to navigate. Today, society leans more towards making promises than delivering. It used to be different, and maybe one day it will be again.

"No bucks, no Buck Rogers", as it goes.
