2025, The New Era of AI! A Complete Guide to the '4 Massive Tectonic Shifts' You Must Know or Get Left Behind
01｜🧠📱 On-Device AI Becomes 'Standard Equipment': Privacy × Responsiveness as Competitive Advantage
What is happening? (Facts)
Apple has formalized an architecture that integrates with on-device processing via 'Private Cloud Compute'. In the announcement for the launch of Apple Intelligence, they explicitly stated policies such as **'data is used only for request execution and is not stored'**. (Apple)
Microsoft has announced and deployed Copilot+ PC. The highlight feature, Recall, officially guides users on 'local processing/local storage/always off/deletable' as part of user control. After a delay prior to launch, the feature design was rebuilt and is now being rolled out in stages for Copilot+ PCs. (Source)
Why is this important?
Whether you can handle personal and business data intelligently without sending it to the cloud is the deciding factor for the user experience. **Authority design/accountability (where processing occurs)** is the watershed moment for adoption.
Practical Checklist for Immediate Action
Policy for on-device support (utilizing iOS/Windows NPU) and explicit indication of processing location
Define minimum privileges for audio, camera, and screen capture, along with opt-out flows
Define criteria for switching **log retention (local/cloud)** for auditing purposes

02｜🎬🔊 "World Generation": AI video x audio becomes mainstream, revolutionizing production & UGC
What is happening? (Facts)
**OpenAI 'Sora 2'** has been announced. Enhanced physical consistency and audio synthesis, and an invitation-only release for the iOS app (initially in the US and Canada) are being reported in Japanese media. (PC Watch)
On Japanese social media, discussions regarding copyright and publicity rights concerning anime-style expressions have intensified. (ITmedia)
Google 'Veo' series developments, such as Veo 3/Flow, have been summarized on the official Japanese blog. (blog.google)
*Availability conditions vary by country/region. As of now (2025/10/03 JST), official reports focus on the start of the Sora 2 app invitation-only release in the US and Canada. Since information regarding general availability in Japan is mixed, please check for official announcement updates. (PC Watch)
Why is this important?
From "filming → editing" to "planning → prompting → refining." Production lead times are shortened, and the frequency of A/B testing increases by orders of magnitude.
Operational design for consent management (e.g., Cameo) and copyright policies is essential.
Immediate Practical Checklist
15–30 second short-form ad prompt templates (duration, composition, CTA)
Creator/Employee consent forms & withdrawal flows (handling of personal likeness)
Clearly define the permissible scope of AI-generated video in brand guidelines

03｜🔎⚡️ Search shifts to 'summarization and execution': AI Overviews/AI mode as a prerequisite
What is happening? (Facts)
AI Overviews were provided in the US in 2024 and expanded to include Japan→on a scale of 100+ countriesin phased rollouts. (Impress Watch)
The provision of AI mode (Japanese) will begin sequentially from September 9, 2025. Official announcement states it can be experienced via the [AI Mode] tab. (blog.google)
Why is this important?
Because summaries, procedures, and comparisons are presented before clicking, there is a paradigm shift from 'SEO competing for blue links' to 'supplying primary information adopted for summaries.'
Structured data (FAQ/HowTo/Product/Review) and clear conclusions are the keys to exposure.
Practical Checklist for Right Now
Add FAQs/procedure tables/comparison tables to major landing pages (HTML structured)
E-E-A-T clarification (author information, primary data, update history)
Add a '**Summary (120 characters) to be picked up by AI summaries**' template to all articles

04｜📜✅ Full-scale Application of Regulations: 'Implementation' is Put to the Test with the EU AI Act and GPAI Code of Practice
What is happening?
The EU AI Act begins phased application from February 2, 2025, with full enforcement scheduled for August 2, 2027. Obligations regarding General Purpose AI (GPAI) begin to apply on August 2, 2025. (www.trendmicro.com)
The European Commission will publish the final version of the GPAI Code of Practice on July 10, 2025. Although it is a voluntary tool, it concretizes compliance practices. JETRO and others have summarized the key points in Japanese. (JETRO)
Why is it important?
Obligations for user companies as well as model providers, regarding risk assessment by use case / data provenance / transparency are spreading.
It is necessary to embed logs and accountability as a 'system' rather than just finishing by 'reading the guidelines'.
Practical Checklist for Right Now
Use Case Ledger (Purpose, Input, Output, Stakeholders, Risks)
Data Provenance & Consent Management (Distinction and recording of synthetic vs. real data)
Impact assessment of model changes(Re-evaluation frequency, alerts, rollbacks)
