# zoo: clever but not as clever as humans

<< Apes' intelligence may be entirely misunderstood, because research has so far failed to measure it fairly and accurately >>

<< Hundreds of scientific studies over two decades have told us that apes are clever – just not as clever as us >>

<< in the last two decades, numerous contemporary researchers in comparative psychology have claimed human superiority over apes in social intelligence, based on two-group comparisons between postindustrial, Western Europeans and captive apes, where the apes have been isolated from European styles of social interaction, and tested with radically different procedures >>

# ai-bot: 352 predictions of when machines will make humans obsolete

researchers at the Oxford University's Future of Humanity Institute  << have carried out the largest-ever survey of machine learning experts on the subject >>

they << contacted 1,634 researchers who published papers at the 2015 NIPS and ICML conferences—the two leading machine learning conferences—and asked them to complete a survey on the topic, with 352 researchers responding >>

<< The aggregate forecast was that there is a 50 percent chance that 'unaided machines can accomplish every task better and more cheaply than human workers' within 45 years >>

per mia opinione (di non esperto AI) se/quando il calcolo quantistico sara' fisicamente capillare e a basso costo come lo e' attualmente l'architettura x86, nel giro di 10-15 anni (anche prima) qualsiasi attivita' umana in qualsiasi distretto geografico del pianeta sara' riproducibile, a velocita', accuratezza, professionalita', fantasia  sorprendentemente superiori e a costi quasi nulli, tendenti a zero.

# gst: something that is called "non-stationarity"

<< “We’re looking at historical data when really we have something that is called non-stationarity,” Dr. Knight [Sandra Knight, a senior research engineer at the University of Maryland and a former official at the Federal Emergency Management Agency] said. “The world isn’t stationary anymore and the hydrology isn’t. The landscape isn’t. So why are we still presuming the future will look like the past?”
