Matters Of Scale:

• “Measuring Massive Multitask Language Understanding”, Hendrycks et al 2020 (introducing new much harder benchmarks to stress-test models—nevertheless, bigger=better: GPT-3 model size vs Q&A, with GPT-3-173b hitting almost 50% out of 4-choice questions vs baseline models like T5 at the random baseline of only 25%)

• “DynamicEmbedding: Extending TensorFlow for Colossal-Scale Applications”, Zeng et al 2020 (embeddings-as-a-service Google-wide; tool AIs want to be agent AIs…)

• “A Time Leap Challenge for SAT Solving”, Fichte et al 2020 (your computer is faster than you think, software+hardware overhang: ~2.5× performance increase in SAT solving since 2000_24ya, about equally due to software & hardware gains, although slightly more software—new software on old hardware beats old on new. See previously Grace2013.)

But some say the condition is not a problem in need of a cure.”, FDA-approved (Savarirayan et al 2020; amusing trivia: the reason why crossing any dog breed with Corgis gives you a Corgified version of that dog breed is because Corgis are homozygous dominant on an FGF4 mutation causing similar achondroplasia as in humans)
