Social media moved us from open forums into gated corporate ecosystems. What began as creative chaos on MySpace and early blogs evolved into attention markets shaped by algorithms and behavioural science. Meme culture emerged as a powerful communication layer, spreading ideas through humour, remix and shared cultures. Influencers became new intermediaries as streaming platforms turned attention into currency. Analytics reshaped communities while concentrating platform power, shifting news and media consumption toward the internet.

Devices transformed computers from stationary tools into an early blueprint for transhumanism. Laptops blurred the boundary between home and work, then smartphones fused daily life with connectivity, GPS, cameras and sensors. The App Store economy unlocked a global software marketplace. Selfie culture emerged as cameras turned inward, reshaping identity and self-expression. Wearables and the Internet of Things extended computing into bodies and environments, while voice interfaces introduced natural interaction. Together, devices reshaped how we see ourselves, others, and our world.

Immersive technologies have expanded computing beyond flat screens into spatial and interactive worlds, but not necessarily lived up to the VR dream. Gaming and real-time 3D engines power simulations, virtual production and digital twins, laying foundations for AR, VR and the path of mixed reality. New hardware, sensors and spatial tracking enabled movement, collaboration and shared environments. These systems support uses from entertainment to engineering and science, while collecting richer behavioural and spatial data for corporations. Haptics, AI worlds and holographic computing hint at the next leap beyond screens.

Beneath the visible layers sits the infrastructure of systems. Authoritarian control, surveillance capitalism and big data transform human consciousness into measurable signals, feeding algorithms and AI models that shape what we see, buy and believe. Identity systems tighten through biometrics and persistent logins. Giant data centres, subsea cables and Starlink networks expand global connectivity. Cloud capitalists rent virtual infrastructure to industries while fintech payment rails move digital money, and regulation of crypto draws us closer to paperless societies.

AI moved from theory to infrastructure almost overnight, faster than the adoption of the web or smartphones. Models now automate reasoning and generation, while agents perform increasingly autonomous tasks across sectors. Vast datasets, specialised chips and immense compute demand bespoke nuclear power grids. AI now helps solve AI challenges, yet its inner workings remain opaque. Ethics, culture and truth lag behind as military capabilities race ahead. Advances in material science enable autonomous cars, robotics and drones, extending AI into the physical world.

The next chapter will be about wet-computing, blending AI with neural-tech and bio-tech in the back-drop of quantum cloud computing. Brain-computer interfaces, external and invasive, are beginning to connect biological systems directly with machines. Brain organoids and neural mapping aim to simulate and potentially upload intelligence to the cloud. Neuroprosthetics may restore body function while cognitive and physical enhancement experiments emerge. These advances raise profound questions about consciousness, life and death, neural data privacy and the ethics of human–machine symbiosis, all unfolding within the ecosystem of capitalism.
