I think this is generally a good thing about Silicon Valley culture.

It’s the reason you get successes like Tesla or SpaceX and it’s generally good to bias towards optimism over pessimism - you get more people able to try more things and successes that have exponential returns make up for the failures.

Otherwise you get stagnation which ends poorly for everyone.

That said, optimism still requires a plan that makes sense and shipping a real product.
