Many people recommend Python, but I also see R, Julia, and Scala mentioned. Which language works best for building real production AI systems?

Data quality is extremely important. In most projects I’ve seen, engineers spend far more time preparing and cleaning data than actually training models. Teams offering ai and data science services usually emphasize this stage because poor datasets can completely undermine even the best algorithms. Investing in data preparation early usually leads to much better long-term results.
