Very funny, this. Did we need forward deployed engineers to convince people that they absolutely need to use the trains in order to "not be left behind"? Or otherwise hype? Or was it sort of obvious and did not need to explained so much - like a bad joke called LLMs ?

Actually- absolutely! Initially, people were really afraid of trains, fearing they wouldn’t be able to breathe at those speeds. It took a lot of convincing to establish trust in the technology.
