A note on working with AI assistants
We are truly living in extraordinary times. With the first appearance of ChatGPT in November 2022 and the continual improvement of these LLMs, the productivity of the knowledge worker has been turbo-charged. The assistance of ChatGPT has dramatically improved how fast I can solve business problems using coding languages I know well such as R, Python, and SQL. But it has also allowed me to develop solutions in code I didn't know well such as web development (HTML, CSS, JavaScript, PHP, etc.).
Luckily for us humans, these LLMs can't easily produce the final solution in a single shot yet, and still often require painstaking back-and-forth effort with the LLM helper to achieve the final result. However, it will be fascinating to watch (and leverage) how AI evolves in the coming years.
