The quote that stayed with me. --- #[fit] Code is a nasty #[fit] byproduct of being #[fit] a software engineer. ^ "Every time you write code, you are introducing the possibility of failure into your system." --- #[fit] 2026 --- #[fit] "Everyone can code" #[fit] ...say those who #[fit] **don't** code. ^ The hype cycle is real. But writing working software is still hard. ---  ^ Andrew Ng: "Just as I think almost everybody should learn to read and write, I think almost everybody should learn to program." --- #[fit] Software #[fit] is **not** solved. ^ Despite all the AI progress, we still need engineers who understand systems. ---  > "The hardest single part of building a software system is deciding precisely what to build." Fred Brooks, The Mythical Man-Month ^ 1975. Fifty years and still the most important sentence in software engineering. --- #[fit] The 3 Skills #[fit] of the **New Dev** --- [.background-color: #1e3a5f] #[fit] 1 --- #[fit] Know how to code. ^ More than ever. You need to master stacks, architecture, the web — to tame metaprogramming tools. ---  # The Pragmatic Programmer Hunt & Thomas, 1999. "Care about your craft. Think about your work." ^ 25 years later, still the foundation. If you can't code, you can't vibe. ---  #[fit] If you don't speak #[fit] the **language**, #[fit] you don't **think** #[fit] in it. ^ "Seven Languages in Seven Weeks" — Bruce Tate. Each language is a way of thinking. --- # Sapir-Whorf Hypothesis To what extent does our language govern our thought process? ^ The language you speak shapes how you think. This applies to programming languages too. --- [.background-color: #1e3a5f] #[fit] 2 --- #[fit] Generalist #[fit] Specialist. ^ The T-shaped professional: deep in one area, broad across many. --- [.background-color: #1e3a5f] #[fit] 3 --- #[fit] Vibe Coding. ^ Andrej Karpathy coined the term in February 2025. "You fully give in to the vibes, embrace exponentials, and forget that the code even exists." --- # What is Vibe Coding? ```python # You describe what you want # The AI writes the code # You review, iterate, ship prompt = "Build a REST API for user auth" result = ai.generate(prompt, context=codebase) ``` ^ It's not about replacing programmers. It's about amplifying them. --- #[fit] The best developers #[fit] are the ones who #[fit] understand **both** #[fit] **worlds**. ^ Code AND AI. Systems AND prompts. Architecture AND vibes. --- # Thank You **Paulo Silveira** paulo.com.br/about ^ First presented at RH Festival StartSe, Sao Paulo, March 2026.
