Early ideas about a global information network did not appear suddenly with the arrival of computers; they grew out of a decades-long conversation among scientists, writers, theologians and engineers. The sources listed above record some of the most explicit forecasts, each framed by the intellectual concerns of its time.

Key anticipations

H. G. Wells’ “World Brain” (1938) imagined “a complete planetary memory” that would be “constantly edited and brought up to date” and made available to every citizen through microfilm reading rooms. Wells saw this as a way to create an informed world public opinion capable of preventing war [2].

Vannevar Bush’s essay “As We May Think” (1945) proposed the Memex, a desk-sized device using microfilm and electronics that would let an individual build “associative trails” through documents. Bush’s mechanism pre-figured both hypertext links and personal workstations [1].

Pierre Teilhard de Chardin’s The Phenomenon of Man (written 1930s-1940s, published 1955) advanced the spiritual-evolutionary concept of the noosphere – a “thinking layer” of the planet that would eventually knit all minds together by means of technology and communication [3].

Douglas Engelbart’s 1968 “Mother of All Demos” showed how several of these ideas could work in practice: real-time text editing, hypertext linking, screen sharing and pointing devices. Engelbart explicitly cited Bush as an inspiration and spoke of augmenting the collective intellect of mankind [5].

Later syntheses, such as Ronfeldt’s survey of noosphere thinking (2020), trace how these pre-digital visions informed the design goals of ARPANET, the Internet and today’s collaborative platforms, while also noting tensions between centralized “world library” models (Wells) and decentralized network ideals (Bush, Engelbart) [4].

Timeline of the discourse

1934–1938 | Wells publishes articles and lectures that become “World Brain”, stirring debate in the British press about whether a universal encyclopedia would empower citizens or impose cultural uniformity [2].

July 1945 | Bush’s essay appears in The Atlantic. Scientists emerging from wartime work discuss how Memex-like tools could keep exploding research literatures manageable [1].

late 1940s-1950s | Teilhard’s writings circulate among intellectuals and are placed on the Vatican’s Index of Prohibited Books even as secular thinkers admire his technological optimism [3].

1950s-early 1960s | Information scientists and librarians cite both Bush and Wells while exploring machine searchable catalogs; the term “hypertext” is coined by Ted Nelson (not in the sources) who points directly to Bush’s associative trails [1][4].

Dec 1968 | Engelbart’s “Mother of All Demos” shocks the computing community and showcases concrete tools for the collective knowledge work envisioned by earlier authors [5].

1970s-1990s | ARPANET, then the Internet, implements packet-switched, decentralized architecture that aligns more with Bush/Engelbart than with Wells’s central encyclopedia, while popular writers revive Teilhard’s noosphere as a metaphor for cyberspace [4].

2000s-present | Scholars such as Ronfeldt reassess these predictions, noting that social media and wikis realise many technical details yet raise new governance issues that Wells and Teilhard anticipated in moral or spiritual terms [4].

Converging and conflicting views

Centralization vs. decentralization: Wells favoured an authoritative, curated repository, whereas Bush and Engelbart stressed individually created, loosely linked knowledge trails. Ronfeldt argues that today’s Internet has elements of both, but its open architecture owes more to the Bush–Engelbart line [2][1][5][4].

Purpose: For Wells the goal was peace through common information; for Bush it was scientific productivity; for Teilhard it was spiritual evolution toward an “Omega Point.” These differing motives shaped how each thinker pictured governance and access [2][1][3].

Spiritual dimension: Teilhard’s explicitly theological noosphere was controversial, prompting both admiration and ecclesiastical censure. Later secular writers borrowed the term while dropping its Christian eschatology [3][4].

Influence on the eventual Internet

Though none of the early thinkers foresaw packet switching or TCP/IP, their conceptual frameworks directly influenced the designers of hypertext, personal computers and collaborative software. Engelbart’s team kept a copy of Bush’s essay pinned to the lab wall, and the term “augmented intelligence” remains a guiding principle in human-computer interaction research [1][5]. Meanwhile, the aspiration for a shared planetary knowledge space continues to echo Wells and Teilhard, now embodied in projects such as Wikipedia and global open data networks [2][3][4].

In sum, the Internet emerged at the intersection of technical invention and a long public conversation about how humanity might pool its knowledge. By tracing that conversation we see that what now feels inevitable was once only an audacious idea in the minds of earlier visionaries.
