Deep Learning Revolution (2012-2020)
Deep Learning Revolution Era
Summary
Section titled “Summary”The deep learning revolution transformed AI from a field of limited successes to one of rapidly compounding breakthroughs. For AI safety, this meant moving from theoretical concerns about far-future AGI to practical questions about current and near-future systems.
What changed:
- AI capabilities accelerated dramatically
- Timeline estimates shortened
- Safety research professionalized
- Major labs founded with safety missions
- Mainstream ML community began engaging
