In this data-driven era, we all know that automation and data scraping are crucial for maintaining competitiveness. However, when you encounter CAPTCHAs, this beautiful vision of automation is often broken. CAPTCHAs, these seemingly simple tests, are actually designed to be difficult for machines to pass. However, as a developer or business leader with a forward-looking vision, you won’t be easily troubled by these small obstacles, right?
