AI AI and web AI and web standards

AI

Students of AI often learn… linguistics, computer science, mathemathics, psychology, neuroscience, philosophy of language, philosophy of science

AI doesn’t mean the same to everyone, it’s an effective phrase to sell ideas

Natural Language Process ng i i i i i i branch of AI concerned with read ng, wr t ng and commun cat ng in human languages (eg speech recognition, machine translation)

Mach ne Learn ng i i i the process in which machines learn to class fy by themselves after being shown a large amount of labelled examples

Generat ve AI i large language models that were trained to generate text, media or code in response to prompts

“word calculators” “near human intelligence”

Agents task-oriented systems that can act on a human’s behalf

human toll data-taggers, people near data centres copyr ght ignored and violated major ethical concerns b as i i i i i accidental or purposefully susta nab l ty magnitudes more water, electricity used

AI and web

i i T he web s open for everyone to read and wr te

LLMs train on the open web

LLMs train on the open web

LLMs put a strain on the web matthiasott.com/articles/webspace-invaders / drewdevault.com

LLMs co-‘author’ the web

LLMs co-‘author’ the web

from: Alexandra Souly ea, Poisoning Attacks on LLMs Require a Near-constant Number of Poison Samples

i T he web s where many access LLMs

i T he web s where consequences of LLM usage are felt

Impl cat ons of AI deployment for web users (the good) Content may be more clear and relevant Easier to find things via more fuzzy search and structured result Very educated guesses at text alternatives i i More useful recommendations

Impl cat ons of AI deployment for web users (the bad) Possible increase of filter bubbles Decreased factuality of web content Security risks of AI agents acting on the web More phishing risk as it is less work i i Cost increase due to lower click through rates
