This pattern shows up often when people are trying to criticize tesla or spaceX. And yeah, if you measure "current reality" vs "promises of their hype man/lead shitposter and internet troll", absolutely. Tesla probably will never achieve full self driving using anything like their current approach. But if you compare Tesla "to other automakers, "to most automakers that ever existed"", or SpaceX to "any rocket company since 1970" there's no comparison. If you're going to compare the internet to pre-internet, compare it to BBS you would access via modem or fax machines or libraries. No comparison.
Similarly you should compare GPT-4 and the next large model to be released, Gemini, vs all AI software for all time. It's no comparison.
which is fine. the bigger topic is, could you leave a religion if the priest's powers were real*, even if the organization itself was questionable?
*real as in generally held to be real by all the major institutions in the world you are in. Most world governments and stock market investors are investing in AI, they believe they will get an ROI somehow.
