Conference Milan 2023

Description:
Before browsers, software was distributed as binary code on physical media. Coding and distribution was difficult and expensive, typically done by big companies on the US west coast. The browser started out as a document viewer, but quickly evolved into a platform for running applications. This technical ship resulted in a democratization and decentralization of software developments. Implication can be seen in many places, probably also in your neighborhood. This talk will examine some of the key moments in the web software platform.

Description:
In this talk, we'll delve into the future of programming and open source in the age of Large Language Models (LLMs). As LLMs rise, text editors may become as extinct as the dodo. Picture a world where software development feels like a casual chat with a witty AI assistant rather than a tedious typing marathon. Expect fresh programming languages and frameworks optimized for LLM generation and large-scale testing. We'll also touch on the transformative path of open source in an AI-driven world. With humor and optimism, Scott will guide us toward an efficient, streamlined, and dare I say, entertaining future of software development.
