IMO being a good technologist entails being skeptical of technologies. Someone has to and should be blindly optimistic, and some people’s jobs borderline depend on it (like VCs) because the risk-reward is asymmetric for them. Overall though, we need to maintain a culture of skepticism around technology — much like scientists do around science. That’s especially true when discussing tech that either: discredits the industry in the eyes of the non-tech public; enables widespread fraud against vulnerable people; or could have significant negative impacts on “the commons” like spam, pollution, reckless political or economic disruption, etc.

"Changing their focus to" vs "appointing themselves as an expert at" are two very different things.

It could be a me issue. Or Crypto could be down?
