New primitives, new beginnings
New computing platforms appear every 7-10 years. Think of "the Web"/Netscape browser (1994), "the cloud"/AWS (2002), iOS/Android (2008) and WeChat (2010-2013). Lots of false-starts in new computing platforms, such as social (remember sheep-throwing apps?), VR/AR and (perhaps) metaverse.
Each new computing platform introduces new primitives for application development. New applications can be built that were not possible before.
iOS/Android came with new primitives such as always-on, automatic location, presence, integrated payments, touch and vertical screen. This led to a massive set of new apps and value migrated from the web to mobile.
LLMs are a new computing platform. New primitives include
NLP-based chat (or prompts & responses) as the main interface
Turning unstructured data/text into structured data/text
Creating (mostly) correct content from prompts
Multi-modal input & output i.e. text, images, audio, video
Easy integration to APIs, applications and websites
Knowing these new primitives is not a sure-shot way of discovering anything new. Just as knowing alwayson/location/payments/touch/vertical screen as new primitives on iOS I don't think helped all of us predict Uber, Zynga, Tiktok in advance.
But it does give developers and risk-taking founders a lot to play with in ways that can reinvent the world.
