> not everyone knows this I actually think far more people know this than done; it wouldn't surprise me if it truly is practically "everyone" on Hacker News. But what is the expectation here? Must every comment thinking about the possibilities or being excited by incremental evidence of support be prefaced with a note of skepticism? Must we engage in such ritualistic behavior in order to be seen as anything other than hopeless scientific romantics? I must pour a bucket of cold water on my own head before feeling even an ounce of optimism? Optimism carries the possible - even likely - cost of disappointment, and in the wrong company can create the same in others. Pessimism is beneficial, but it doesn't have to be worn on one's sleeve at all times lest it sap joy and color from the world. This is a community of enthusiasts, we can be enthusiastic without also being hopeless idiots lurching from one false discovery to the next.
