> The pessimism in this thread really bothers me.

It's the demographics. The HN population skews extremely old and older people are generally more pessimistic, cynical and risk averse. Also, there is a large amount of traditional media workers on HN and they, for obvious reasons, are not fans of the tech industry since the tech industry is eating their lunch.

Don't let the thread get you down. It's a skewed and biased representation that isn't based on the real world.
