Morning, Matt. The morning slug sits at the seam between two worlds. On one side, the pace of AI-driven change is outrunning the humans in the loop — a Zenn engineer admits they now ship 500+ commits a day and have effectively stopped reading diffs, while another Zenn author builds a whole second brain on a single Android phone with Obsidian, Termux, Claude, and ChatGPT. On the other side, the weight of legacy is still the dominant constraint on Japan’s enterprise stack: Fujitsu and IBM Japan are formally teaming up to help companies escape COBOL, and security teams are quietly walking away from site-to-site VPNs toward Zscaler’s zero-trust-style model. JETRO’s morning set rounds it out with two international notes — Hyundai’s revenue-is-up-but-operating-profit-is-down-20% quarter in Korea, and a US Arkansas "food theater" reframing Japanese cuisine as an experience rather than a meal. The throughline: whether the topic is food, code, security, or a 1970s mainframe language, Japan is busy rewriting the contract between what was built and what comes next.

• 現代自動車、第2四半期の売上高は増加するも営業利益は2割減(韓国) (ジェトロ ビジネス短信) — Hyundai Motor posted higher Q2 revenue but operating profit fell roughly 20% year over year. The Korea-side read paints a margin-squeeze picture even as top-line growth holds. (In Japanese Language)
• 「食べる」から「体験」する日本食の提供へ、米アーカンソー州のフード・シアターがイベント開催(米国) (ジェトロ ビジネス短信) — A US Arkansas "food theater" hosted an event reframing Japanese cuisine from something you eat into something you experience. The Angle: culinary soft-power moving from plate to performance. (In Japanese Language)
• 1日500コミットは、もう読めない ── だからコードレビューをやめた (Zennのトレンド) — With agents running in parallel, the author now ships over 500 commits a day — and admits they rarely actually read the diffs anymore, occasionally skipping runtime checks as well. Despite that, simple bugs almost never appear, because the things that only code review used to catch were eliminated upstream. The post walks through what was engineered to make that possible.

• スマホでつくるセカンドブレイン(Android・Obsidian・Termux・Claude・ChatGPTによる知識管理) (Zennのトレンド) — Inspired by earlier articles, the author wanted a durable home for AI chat histories, decision logs, and several personal projects, and built an Android-only setup around Obsidian, Termux, Claude, and ChatGPT for use during commute-time gaps. The write-up walks through the environment they assembled. (In Japanese Language)
• もう「拠点間VPN」は安全じゃないのか？ 代替手段が浮上するのはなぜか (＠IT NewsInsight 最新記事一覧) — Site-to-site VPNs have long been the default for secure inter-organization links, but the article argues the approach carries hidden risk. Zscaler’s model is framed as a different mental model for network security rather than a thicker VPN tunnel. (In Japanese Language)
• 富士通と日本IBMが「COBOL脱却」でタッグ 移行先はJava 企業をどう支援？ (＠IT NewsInsight 最新記事一覧) — With Fujitsu’s mainframe business winding down, migrating existing COBOL assets is now a top management priority. Fujitsu and IBM Japan have announced a partnership specifically aimed at helping enterprises exit COBOL, with Java as the target platform — the article unpacks what’s inside the deal.
