Digital Skills Development

Even though I’m a much better Python than JavaScript developer, with AI assistance, I’ve been writing a lot of JavaScript code recently. AI-assisted coding, including vibe coding, is making specific programming languages less important, even though learning one is still helpful to make sure you understand the key concepts. This is helping many developers write code in languages we’re not familiar with, which lets us get code working in many more contexts! My background is in machine learning engineering and back-end development, but AI-assisted coding is making it easy for me to build front-end systems (the part of a website or app that users interact with) using JavaScript (JS) or TypeScript (TS), languages that I am weak in. Generative AI is making syntax less important, so we can all simultaneously be Python, JS, TS, C++, Java, and even Cobol developers. Perhaps one day, instead of being “Python developers" or “C++ developers,” many more of us will just be “developers”! But understanding the concepts behind different languages is still important. That’s why learning at least one language like Python still offers a great foundation for prompting LLMs to generate code in Python and other languages. If you move from one programming language to another that carries out similar tasks but with different syntax — say, from JS to TS, or C++ to Java, or Rust to Go — once you’ve learned the first set of concepts, you’ll know a lot of the concepts needed to prompt an LLM to code in the second language. (Although TensorFlow and PyTorch are not programming languages, learning the concepts of deep learning behind TensorFlow will also make it much easier to get an LLM to write PyTorch code for you, and vice versa!) In addition, you’ll be able to understand much of the generated code (perhaps with a little LLM assistance). Different programming languages reflect different views of how to organize computation, and understanding the concepts is still important. For example, someone who does not understand arrays, dictionaries, caches, and memory will be less effective at getting an LLM to write code in most languages. Similarly, a Python developer who moves toward doing more front-end programming with JS would benefit from learning the concepts behind front-end systems. For example, if you want an LLM to build a front end using the React framework, it will benefit you to understand how React breaks front ends into reusable UI components, and how it updates the DOM data structure that determines what web pages look like. This lets you prompt the LLM much more precisely, and helps you understand how to fix issues if something goes wrong. Similarly, if you want an LLM to help you write code in CUDA or ROCm, it helps to understand how GPUs organize compute and memory. [Reached length limit; full text: https://lnkd.in/dS_buaTu ]

Someone messaged me on LinkedIn to tell me that a quiz for my Python course (Python Essential Training) was wrong. It was a multiple choice question, asking the result of five lines of Python code. They took a screenshot of the question, sent it to an LLM, and the LLM gave them the wrong answer. I typed the five lines into the terminal, ran it, and got the correct result. This could also be done in Jupyter Notebook or an IDE if you wanted to rewrite the code and mess around with it for additional learning. Look: I love LLMs. I make thousands or millions of OpenAI requests a day for work (with prompts I spent months developing), bounce ideas off of Gemini, use Copilot as a glorified auto-complete. Great stuff. But at *some point* I mean... SOME point, when you are learning to program, you have to: - Understand what all the words and symbols mean - Type the code yourself into something that's connected to a plain interpreter/compiler and not a fancy linear algebra machine that probability-distributes a result back to you. - Learn to read and write code through repeated (REPEATED) practice. Yes, I understand that math teachers looked like idiots when calculators became cheap and ubiquitous ("Haha, now I *do* have a calculator with me at all times!") and this is often used as a comparison to LLMs and programming. But there are a few things to consider here: - You still need a mental estimate to check that you didn't typo a number - You need to know how to set up the equation - You need to do these things even with a machine that ACTUALLY computes. Calculators are "arithmetic machines." Conversely, LLMs just predict. They are syntactic probability machines, not programmers or compilers. This places an even greater responsibility on the programmer. LLMs are great tools for programming, but, at the end of the day, you still have to learn how to do it. If you use ChatGPT in a course you need to make sure that it's aiding your learning rather than replacing it. And, listen, you don't have to take my word on any of this. If you don't think programming will be a useful skill in the future, great. But then... don't take a programming course? We'll be here to fix your codebase when it falls apart.

We know LLMs can substantially improve developer productivity. But the outcomes are not consistent. An extensive research review uncovers specific lessons on how best to use LLMs to amplify developer outcomes. 💡 Leverage LLMs for Improved Productivity. LLMs enable programmers to accomplish tasks faster, with studies reporting up to a 30% reduction in task completion times for routine coding activities. In one study, users completed 20% more tasks using LLM assistance compared to manual coding alone. However, these gains vary based on task complexity and user expertise; for complex tasks, time spent understanding LLM responses can offset productivity improvements. Tailored training can help users maximize these advantages. 🧠 Encourage Prompt Experimentation for Better Outputs. LLMs respond variably to phrasing and context, with studies showing that elaborated prompts led to 50% higher response accuracy compared to single-shot queries. For instance, users who refined prompts by breaking tasks into subtasks achieved superior outputs in 68% of cases. Organizations can build libraries of optimized prompts to standardize and enhance LLM usage across teams. 🔍 Balance LLM Use with Manual Effort. A hybrid approach—blending LLM responses with manual coding—was shown to improve solution quality in 75% of observed cases. For example, users often relied on LLMs to handle repetitive debugging tasks while manually reviewing complex algorithmic code. This strategy not only reduces cognitive load but also helps maintain the accuracy and reliability of final outputs. 📊 Tailor Metrics to Evaluate Human-AI Synergy. Metrics such as task completion rates, error counts, and code review times reveal the tangible impacts of LLMs. Studies found that LLM-assisted teams completed 25% more projects with 40% fewer errors compared to traditional methods. Pre- and post-test evaluations of users' learning showed a 30% improvement in conceptual understanding when LLMs were used effectively, highlighting the need for consistent performance benchmarking. 🚧 Mitigate Risks in LLM Use for Security. LLMs can inadvertently generate insecure code, with 20% of outputs in one study containing vulnerabilities like unchecked user inputs. However, when paired with automated code review tools, error rates dropped by 35%. To reduce risks, developers should combine LLMs with rigorous testing protocols and ensure their prompts explicitly address security considerations. 💡 Rethink Learning with LLMs. While LLMs improved learning outcomes in tasks requiring code comprehension by 32%, they sometimes hindered manual coding skill development, as seen in studies where post-LLM groups performed worse in syntax-based assessments. Educators can mitigate this by integrating LLMs into assignments that focus on problem-solving while requiring manual coding for foundational skills, ensuring balanced learning trajectories.

It’s tempting — you describe a task, and the LLM writes the code for you. Feels magical, right? But here’s the catch 👇 🚫 No Deep Understanding: If you skip learning the logic behind the code, you’ll struggle to debug or optimize it when things break (and they will). 🚫 Limited Problem-Solving Growth: Coding isn’t just about syntax — it’s about thinking in systems. When an LLM does that thinking for you, your analytical edge fades. 🚫 Dependency Trap: You start relying on the model for even the simplest logic. The skill that once made you valuable — structured problem-solving — erodes over time. 🚫 Innovation Requires Intuition: Great developers innovate because they understand — data structures, algorithms, patterns, trade-offs. No model can replicate that human intuition. 💭 LLMs are incredible assistants, not replacements. Use them to accelerate learning, not avoid it. Master the craft first. Then let AI amplify your skill — not replace it. #genai #AI #Coding #LLM #DeveloperGrowth #ArtificialIntelligence #Productivity #Learning

"This report covers findings from 19 semi-structured interviews with self-identified LLM power users, conducted between April and July of 2024. Power users are distinct from frontier AI developers: they are sophisticated or enthusiastic early adopters of LLM technology in their lines of work, but do not necessarily represent the pinnacle of what is possible with a dedicated focus on LLM development. Nevertheless, their embedding across a range of roles and industries makes them excellently placed to appreciate where deployment of LLMs create value, and what the strengths and limitations of them are for their various use cases.  ... Use cases We identified eight broad categories of use case, namely: - Information gathering and advanced search - Summarizing information - Explaining information and concepts - Writing - Chatbots and customer service agents - Coding - code generation, debugging/troubleshooting, cleaning and documentation - Idea generation - Categorization, sentiment analysis, and other analytics ... In terms of how interviewees now approached their work (vs. before the advent of LLMs), common themes were: - For coders, less reliance upon forums, searching, and asking questions of others when dealing with bugs - A shift from more traditional search processes to one that uses an LLM as a first port of call - Using an LLM to brainstorm ideas and consider different solutions to problems as a first step - Some workflows are affected by virtue of using proprietary tools within a company that reportedly involve LLMs (e.g., to aid customer service assistants, deal with customer queries) ... Most respondents had not developed or did not use fully automated LLM-based pipelines, with humans still ‘in the loop’. The greatest indications of automation were in customer service oriented roles, and interviewees in this sector expected large changes and possible job loss as a result of LLMs. Several interviewees felt that junior, gig, and freelance roles were most at risk from LLMs ... These interviews reveal that LLM power users primarily employed the technology for core tasks such as information gathering, writing, and coding assistance, with the most advanced applications coming from those with coding backgrounds. Although users reported significant productivity gains, they usually maintained human oversight due to concerns about accuracy and hallucinations. The findings suggest LLMs were primarily being used as sophisticated assistants rather than autonomous replacements, but many interviewees remained concerned that their jobs might be at risk or dramatically changed with improvements to or wider adoption of LLMs. By Jamie Elsey Willem Sleegers David Moss Rethink Priorities

"Will AI coding assistants replace AI engineers in 5 years?" ⬇️ My friend Drazen Zaric asked me this question over coffee, and it got me thinking about the future of AI engineering—and every other job.
