A Perspective on Large Language Models, Intelligent Machines, and Knowledge Acquisition

TL;DR

This paper examines the capabilities and limitations of Large Language Models like GPT-4 in understanding and reasoning, contrasting them with human knowledge acquisition and discussing implications for education.

Contribution

It provides a philosophical analysis of LLMs' abilities, highlighting their imitation of reasoning without true understanding, and discusses their impact on human knowledge and learning.

Findings

GPT-4 can imitate reasoning but lacks true understanding

LLMs synthesize knowledge from vast data, unlike humans

Limitations of LLMs affect their role in education

Abstract

Large Language Models (LLMs) are known for their remarkable ability to generate synthesized 'knowledge', such as text documents, music, images, etc. However, there is a huge gap between LLM's and human capabilities for understanding abstract concepts and reasoning. We discuss these issues in a larger philosophical context of human knowledge acquisition and the Turing test. In addition, we illustrate the limitations of LLMs by analyzing GPT-4 responses to questions ranging from science and math to common sense reasoning. These examples show that GPT-4 can often imitate human reasoning, even though it lacks understanding. However, LLM responses are synthesized from a large LLM model trained on all available data. In contrast, human understanding is based on a small number of abstract concepts. Based on this distinction, we discuss the impact of LLMs on acquisition of human knowledge and education.
