iPhone 17 Pro가 400B MoE 모델을 0.6 tok/s로 구동했고, Mozilla AI는 에이전트끼리 지식을 공유하는 'cq'를 공개했다. 50년간 모든 regex 엔진의 전체 매치가 O(n²)였다는 사실이 재조명됐고, Resolv DeFi 해킹은 오프체인 키 하나로 $23M이 증발할 수 있음을 보여줬다. Claude는 컴퓨터를 직접 조작하기 시작했다.

Flash-MoE가 397B MoE 모델을 48GB MacBook에서 4.4 tok/s로 돌렸고, 바이브 코딩의 한계와 추상화의 가치가 재조명됐다. BitTorrent 창시자 Bram Cohen이 CRDT 기반 버전 관리 Manyana를 공개했고, Walmart은 ChatGPT 내 결제 전환율이 3배 낮다고 인정했다. GitHub의 가용성이 3나인도 위태롭고, POSSE와 Project Nomad가 웹 독립성 운동을 다시 불러왔다.

JavaScript 의존성 블로트의 세 기둥이 2026년에도 건재하고, GPT-5.2와 Claude Opus 4.6이 '무(無)'를 입력받으면 동일하게 침묵하는 현상이 발견됐다. Cloudflare가 archive.today를 C&C 봇넷으로 판정해 DNS를 차단했고, WebGPU+WASM 조합이 브라우저 영상 편집을 프로 수준으로 끌어올렸다. 3M의 PFAS 철수가 데이터센터 냉각 공급망에 충격파를 주고, C++26 contracts 최종 회의에서는 여전히 합의가 갈린다.
