Tonight's Japan tech picture is a study in independence and honesty. AWS and Google are now shipping their own PyTorch builds for Trainium and TPUs, a concrete step toward loosening NVIDIA's hold on AI hardware. At the same time, Japanese security experts are pushing back on a convenient excuse: the ARTEX attack tool may be new, but the doors it walked through were old ones. And while the AI boom rolls on, Apollo's chief economist argues the economic payoff outside big tech is still barely visible — a useful cold shower. The counterweight is practical: GMO's 150-agent BPO service and Google's new Genkit Agents API both put humans and agents on the same team, and a new language called Goose claims to outrun C++ and Rust. Less hype, more plumbing — that's where the real shift is happening.

Topics in this Spud’s Japan View

1. AWSとGoogle Cloudが「PyTorch」のAWS Trainium、Google Cloud TPU対応版をオープンソースで公開。NVIDIAからの移行に挑む
   (AWS and Google Cloud open-source PyTorch builds for AWS Trainium and Google Cloud TPUs, challenging NVIDIA's dominance)
   (Publickey)
   AWS and Google Cloud each unveiled open-source PyTorch editions tuned for their own AI processors at PyTorch Conference 2026, held October 20–21 in California, in a direct bid to make it easier for developers to move AI workloads off NVIDIA hardware. The announcements put the two cloud giants' Trainium and TPU chips on a more equal footing with the framework most AI researchers already use.
2. 日本企業が「サイバー攻撃はAIのせい」にして目を背ける“本当の原因”
   (The real cause Japanese firms ignore while blaming AI for cyberattacks)
   (ITmedia AIT Security)
   Experts cited in the report say the autonomous AI attack tool ARTEX was linked to a string of breaches at Japanese companies, but the intrusion routes it exploited were conventional ones that have long been known. The piece argues that blaming AI lets firms look away from the unglamorous work of patching and hardening the basics, and it gathers concrete measures for closing those familiar gaps.
3. 大手テクノロジー企業以外ではAIへの投資による経済的利益がほとんど得られていないとの指摘
   (Almost no economic payoff from AI investment outside big tech, report argues)
   (GIGAZINE)
   Apollo chief economist Torsten Sløk argues in a new report that AI has brought essentially no economic benefit to American companies outside the technology industry, despite heavy spending on AI tools and agents. The claim cuts against the broad productivity narrative and raises the question of whether the gains so far are concentrated in the companies selling the picks and shovels.
4. C++やRustよりも高速に動作しメモリ使用量も少ないプログラミング言語「Goose」
   (“Goose,” a programming language that runs faster than C++ and Rust while using less memory)
   (GIGAZINE)
   Goose is a system programming language developed with AI assistance that its creators say combines memory safety, exceptional execution speed, and compact memory usage, beating established languages such as C++ and Rust in benchmarks. If those results hold up outside the lab, it could give systems programmers a faster, safer alternative to the current incumbents.
5. GMOランシステム、150種以上のAIエージェントと人が連携するBPOサービスを提供開始
   (GMO RunSystem launches a BPO service pairing more than 150 AI agents with people)
   (IoTNEWS)
   GMO RunSystem, part of the GMO Internet Group, has launched the BPO service “GENBA AI by GMO,” in which more than 150 kinds of AI agents handle routine accounting, human-resources, and inquiry work while people take on exceptions and final checks. The model is explicitly a partnership rather than a replacement: agents do the volume, humans keep the judgment.
6. GoogleのGenkit、TypeScriptとGo向けに「Detached Turns」と「Human-in-the-Loop」機能を備えたAgents APIをリリース
   (Google's Genkit releases an Agents API for TypeScript and Go with Detached Turns and Human-in-the-Loop features)
   (InfoQ Japan)
   Google has released a preview Agents API for Genkit, its open-source foundation for building full-stack AI applications, unifying message history, tool-execution loops, streaming, state persistence, and a front-end protocol behind a single chat() interface. The preview supports TypeScript and Go, with Python and Dart support planned, and its Detached Turns and Human-in-the-Loop features are aimed at agents that run longer and know when to ask a person.
