Lobste.rs user seeks AI/ML roadmap after 2018-19 hibernation

The request comes from someone who describes being on hibernation since the 2018-19 time frame, meaning they missed the period in which large language models moved into wide use. They are not asking for a single answer but for a structure — something like TeachYourselfCS — that would let them navigate the field's accumulated knowledge rather than piece it together from scattered sources. They also raise a practical distinction: whether understanding LLMs requires a different approach from the ML models that were already in large-scale deployment before 2022/21. That question suggests the user suspects the recent wave may not be fully covered by older learning paths. How useful the community's replies turn out to be may hinge on whether they address that split directly, rather than offering a single generic list.
