Google launches Gemini 3 and wires it straight into Search

Google released Gemini 3, its most advanced model so far, with stronger reasoning, deep multimodal understanding and agentic capabilities — and turned it on in Google Search from day one via AI Mode.

Gemini 3 beats ChatGPT-5.1 in early head-to-head tests

Tech reviewers running side-by-side trials report Gemini 3 winning the majority of rounds against ChatGPT-5.1 on tasks like creative constraint-following, UX design thinking, critical analysis and cross-domain reasoning, often being judged the “clear winner” for everyday use.

By 2030, 100% of IT work will involve AI in some way

A new Gartner survey of 700+ CIOs finds 0% of IT work will be done without AI, with 75% done by humans augmented with AI and 25% by AI alone — implying every IT organisation needs a joint AI-readiness + human-readiness plan this decade.

Gartner warns of “jobs chaos” as AI and humans recombine

Rather than a jobs apocalypse, Gartner forecasts a period of “jobs chaos” from 2028–2029 as over 32 million roles per year are reconfigured, splintered or fused due to new human–AI collaboration patterns.

Bitcoin drops below $90,000, erasing 2025 gains

Bitcoin fell under $90K for the first time since April, down nearly 30% from its October peak above $126K, before bouncing slightly — a move analysts link to fading rate-cut hopes and broad risk-off sentiment hitting both crypto and AI stocks.

Crypto market wipeout: over $1–1.2 trillion in value gone since early October

Across major coins, the market has shed roughly $1.1–1.2 trillion in a matter of weeks, driven by high-leverage unwinds, macro jitters and what traders are now calling the “10/10” liquidation event that triggered record leveraged flush-outs.

Ethereum and majors mirror the slide

Ethereum has fallen around 40% from its recent highs, breaking below the psychologically important $3,000 level, while analysts highlight broken support levels and warn that further downside is possible if tech-sector and rate fears persist.

Volatility reshapes investor behaviour

Coverage notes that this downturn has erased most of 2025’s gains and pushed many smaller tokens much deeper into the red, with some institutional and retail investors rotating toward cash, stablecoins or sitting on the sidelines until volatility cools.
