How Technology Changed the World in My Lifetime
This opinion piece reflects on how information technologies—particularly the internet, social media, smartphones, and more recently AI/LLMs—have already transformed everyday life over the author’s lifetime. The author contrasts rapid recent AI-driven shifts in software with earlier, widespread changes driven by online social platforms: more screen time, new social bonds formed across distance, GPS navigation eliminating much of 'getting lost', pervasive archival memory of online actions, and ubiquitous on‑demand knowledge via Google, Wikipedia and YouTube. The essay argues these technological changes reshape social organization, privacy, identity, and what counts as valuable human knowledge and skill, and suggests AI may bring further, still-unfolding disruption.
The essay contextualizes long-term, technology-driven shifts (social platforms, smartphones, on-demand knowledge, and emerging AI) that shape audience behavior, privacy norms, and the operating environment for advertising and measurement—useful strategic context for AdTech but not a direct industry action or breaking event.

Essay Argues Smartphones Enabled a Global 'Hive Mind'
A Noahpinion essay (published 2026-06-11) argues that smartphones — especially when paired with social media platforms — transformed the internet from a decentralized space into a persistent, attention-grabbing "hive mind." The piece cites academic experiments (Bursztyn et al. 2024; Castelo et al. 2025) that document users' unwillingness to leave popular platforms and measurable mental-health and attention benefits from removing mobile internet access. The author links the constant presence of smartphones to rising youth unhappiness, erosion of in-person social interaction, and broader sociological effects such as lowered fertility trends, framing smartphones themselves (not just apps) as a structural driver of these changes.
The Internet Has Become Real Life
An a16z opinion newsletter argues that the internet now sits upstream of American life — shaping news cycles, politics, music, film, language and cultural coordination. The piece describes how social platforms (notably TikTok) change creative formats (e.g., 15‑second hooks for music), how movies and politics increasingly target online subcultures, and how memetic discourse alters political language and priorities. The author also introduces "Monitoring the Situation" (MTS), described as a timeline‑native, always‑on news network aimed at tracking tech, finance, geopolitics and culture.
AI Enables the Most Human Technology: Making
An a16z opinion essay argues that AI is not only a time-saving tool but also a uniquely human technology that expands people's ability to create. The author contrasts consumption-focused technologies with tools that enable making, saying AI lowers the cost of experimentation and lets non-programmers build useful software. The piece offers anecdotal examples — an electrician who built a $12.99 load-calculation tool and a plumber who canceled a $40,000 consulting contract after using an AI tool — to illustrate how AI democratizes creation in both work and leisure. The essay rejects dystopian centralization as the dominant outcome, predicting instead more individuals building small, meaningful projects and a cultural shift toward
