Start with a question
Real questions people have about AI — answered with the same sourcing and honesty as everything else here. Pick the question you actually arrived with; each one opens the page that answers it.
What are the biggest concerns people raise about AI today?
Safety, bias, accountability and the effect on work — the research, the watchdogs and the critics, with sources you can read yourself.
Who are the leading voices in AI — and what do they actually disagree about?
Frontier lab leaders, safety researchers, critics and everyone in between — each with their stated positions, presented without picking a side.
What do all these AI terms actually mean?
Every term explained in plain language, with where it came from — and an honest note when nobody can be credited with coining it.
Is AI going to affect my job? What should I actually prepare for?
What the research says about automation, labor and changing roles — plus the free training worth your time while the picture is still moving.
What's happening in AI right now?
Live headlines from dozens of free public publications, newest first, with the paywall and ownership caveats stated plainly.
AI and your job
What the current numbers show
Use, task exposure, and employment projections measure different things. None of these figures is a count of jobs AI will eliminate.
Observed use
40%
of US employees reported using AI at work
Up from 20% in 2023. This is reported use, not a count of jobs changed or replaced.
Anthropic Economic Index, September 2025Observed use

augmentation versus automation in Claude.ai work conversations
Claude.ai usage leaned toward people working with AI rather than handing over a task entirely.
Anthropic Economic Index, February 2025Exposure estimate
1 in 4
workers globally are in occupations with some generative-AI exposure
Only 3.3% of global employment is in the highest exposure category. Exposure means task overlap, not job loss.
ILO refined global exposure index, May 202510-year projection
+5.9M
US jobs projected across the whole economy from 2025 to 2035
Total employment is projected to grow 3.5%, from 170.3 million to 176.2 million. This is not an AI-only forecast.
