I don’t know what gives you the impression that course duration somehow equates to course quality.
An educational resource existing for less cost and longer duration doesn’t translate into anything real without quality ciriculum and instruction.
A lot of content on both YouTube and Udemy is…not great. And even then not necessarily curated in a certain way, etc.
Furthermore, courses like this in general often are geared at developers/engineers who are already employed and could even get reimbursement/coverage for from their employer, which offsets or eliminates the cost entirely.
