>"faith" is the proper description since just like an alchemist, you have no evidence or functioning example to justify your belief.
It's not faith. Over the past 25 years and especially the last 5 years boxes of sand have again and again shown themselves capable of tasks that previously were thought to only be tractable with true intelligence. Problems answerable only in the sole domain of humans, or would at least remain so for long into the distant future. Chess playing is an early example from the 80s and 90s. In 2010 we thought Go would take at least a decade to automate, but by 2015 the best human players were rendered inferior. Art was long thought to be impossible for a machine, today I can create a custom Mona Lisa image in seconds. Organizing an archive of photos based on subject matter or the persons present in them used to take many human hours of labor, now Google Photos does it automatically for free. There are comments here on HN from 3-4 years ago when transformer LLMs were first materializing saying they're cool but unlikely they'll ever be able to synthesize anything useful or which remains congruent for several sentences much less pages. Today I save hours of work each month summarizing meeting discussions, generating complex standard expressions, and breaking through creative blocks.
Yet there is still dismissive handwaving, declaring these technologies mindless piles of silicon completely incapable of intelligence. If that's really true then clearly we have no idea what intelligence actually is. If you showed ChatGPT and DALL-E and the other software of today to people in 1975 they would say with near-unanimity that we invented intelligent machines.
