Coursera used to be great, the value was unparalleled. Great specializations too; I learned Python and data science techniques through the platform during the COVID pandemic. Lately though they've been pushing for courses to have AI dialogue modules, where an AI agent asks you questions about the content. These modules are absolute slop garbage, often asking repetitive questions that have no grounding in actual course content. I got sick of this and dropped my subscription about a month ago.
