This work demonstrates reservoir computing via a 3D stack that couples In2Se3 photodetectors with MoS2 memtransistors. The top tier exploits thickness-dependent photoresponse of In2Se3 flakes to form an optical reservoir, while the bottom tier uses programmable MoS2 memtransistors to convert photocurrent into photovoltage and feed a trained readout circuit also based on MoS2 devices. The devices are placed with sub-50 nm proximity, enabling near-sensor information processing and faster photoresponse calibration. This edge-oriented approach highlights the potential of vertically stacked heterogeneous materials beyond silicon for compact, energy-efficient intelligent sensing and computing systems, advancing monolithic 3D integration (M3D) paradigms.

November 23, 2025, 3:36 AM EST. During an internal all-hands session reviewed by Business Insider, Nvidia CEO Jensen Huang warned that market sentiment has put the company in a no-win scenario: miss = evidence of an AI bubble, beat = fuel for one. Despite a blockbuster quarter and raised guidance, the stock swung from an early rise to a pullback as the broader AI trade cooled. Nvidia reported strong demand for data-center GPUs and reiterated guidance with visibility into half a trillion dollars of future revenue. The reaction mirrors a market wary of expensive AI infrastructure bets and debt-heavy financing, amid macro jitters and Fed-policy uncertainty. As earnings season winds down, investors debate whether AI hype can sustain the pace of capital expenditure and revenue growth.

November 23, 2025, 3:34 AM EST. In US antitrust proceedings over Google's digital advertising business, a judge signaled reluctance to order a breakup of the Google Ads unit. The hearing focused on whether a structural remedy is necessary to curb potential anticompetitive behavior or if a narrower rulemaking would suffice. Lawyers argued over how to define the relevant market and what remedies would avoid harming consumers and publishers. The judge's hesitation suggests the court may favor interim or behavioral remedies rather than a full monopoly breakup, potentially delaying a final ruling. The outcome will influence how regulators pursue enforcement in the digital advertising market and could set precedent for future tech antitrust actions in the US.

Ubisoft debuted Teammates, a playable AI research project at GDC 2024 that features Jaspar, an in-game AI voice assistant, and two NPCs, Sofia and Pablo, who respond to real-time voice commands. The experiment aims to deepen immersion by interpreting natural speech to highlight enemies, adjust settings, pause the game, or coordinate actions during an FPS-style mission. Players guide Sofia and Pablo through cover and attacks in a dystopian base as they search for missing teammates. The project, led by Gen AI Director Xavier Manzanares, Narrative Director Virginie Mosser, and Data & AI Director Rémi Labory, emphasizes context-aware interactions and testing what is possible when player voice becomes a core gameplay mechanism.

November 23, 2025, 3:30 AM EST. At PwC, 26-year-old Donald King helped build AI agents after the firm pledged a $1 billion AI push, joining an internal AI factory and logging 60-80 hour weeks. He hosted knowledge-sharing AI agent sessions and won first place in an OpenAI hackathon. Yet the same technology that automates tasks raised questions about job security. In October 2024, days after presenting his hackathon project, King was unexpectedly laid off. He posted the moment on TikTok, drawing millions of views and fueling a debate about whether AI advances could drive further staff cuts in consulting and other sectors. The episode highlights the tension between AI innovation and workforce security.
