ChatGPT

ChatGPT is OpenAI's large language model-powered conversational " product, first released in November 2022 and now one of the most " widely adopted AI tools across professional and consumer contexts. " In the context of the AI jobs and labour disruption story, ChatGPT " serves as the benchmark public reference point for AI professional " capability: it passed the bar exam at the 90th percentile, scored " highly on the CFA Level I exam, and outperforms the average human " on dozens of professional credentialling tests , directly relevant " to the Goldman Sachs research finding that early-career workers " face 10 percentage points lower real earnings over the " following decade when displaced during their credential-building " years.

Launched in late 2022, ChatGPT reached 100 million users in two " months , the fastest consumer product to that threshold in history. " GPT-4o (released 2024) extended capability to voice, vision, and " reasoning tasks. By April 2026, ChatGPT has become the de facto " public reference for what general-purpose AI can do across " knowledge work, with a user base measured in hundreds of millions " and enterprise integrations across legal, financial, and medical " sectors. Anthropic's LLM adoption research found professional " Claude usage covering 75% of computer programmers' tasks , a figure " that applies similarly to ChatGPT in its deployment contexts.

The displacement risk associated with ChatGPT is distinct from the " cybersecurity-focused threat of Claude Mythos Preview. ChatGPT " threatens credential-dependent professions , law, finance, " consulting, writing , by performing credentialled knowledge work at " a fraction of the cost. The Goldman Sachs finding that early-career " displacement causes decade-long earnings scarring is particularly " relevant here: the workers most at risk of ChatGPT substitution are " those at the entry level of credentialled professions, precisely the " cohort whose career trajectories are most sensitive to early-career " interruption.
