Evolution of Artificial Intelligence

TL;DR

• AI started in the 1950s when pioneers like Alan Turing and John McCarthy asked whether machines could think.
• Early decades saw bursts of optimism followed by "AI winters" when progress fell short of expectations.
• Key breakthroughs — backpropagation, larger datasets, faster hardware — kept the field moving forward.
• From the 2010s, deep learning transformed vision, speech, and language; systems like AlphaGo, GPT, DALL-E, and ChatGPT made AI feel real.
• By 2024-2026, models became multimodal (text, images, audio, tools) and agentic (planning and acting across multi-step tasks).
• The focus has shifted from raw capability to usefulness, reliability, safety, and accountability.
