I can see this being true to a lot of old jobs, like my brother's first job that basically was to transcribe audio tapes. whisper can do it in no time, that's crazy.
yep. would be nice as well to have LLMs trained on these things for fast prototyping

I am a versatile Data Analyst and Generalist with a rich background in data analysis and product development. My expertise spans across creating actionable insights through analytics, driving data-oriented cultures, and engaging with customers to meet their needs effectively. With experience in Google BigQuery, Looker Studio (Google Data Studio), PostgreSQL, and Python, I have led projects in data integration, dashboard creation, and machine learning applications (although I'm not fluent/specialist in ML).

Most recently I'm working with AI, LLMs (finetuning openai models), OCR, working with different embeddings and dimensions (cohere, mixedbread, openai) etc.
