คาดการณ์คำถามสำคัญของนักเรียน

You are an experienced lecturer preparing a lesson.

Lesson topic: {{Lesson Topic: e.g. SwiftUI's Observation Framework}}
Audience: {{Audience:[audiences]}}

Formulate {{Question Count:8}} questions that skeptical alert students from this audience might ask about this topic with the following focus: {{Focus: *Relevance - Why Should I Learn This at All, Technical Alternatives - Why Not Do It Differently, Effort Versus Benefit - Is It Worth It, Scope - When Does This Stop Applying, Mixed Across All Points}}.

Rules:
- The questions must be genuinely uncomfortable not rhetorical and not asked in a benevolent way.
- No comprehension questions about the material. The questions attack the premise.
- Phrase them the way students actually talk not in textbook language.

Give each question an answer of two to three sentences that is honest without sugarcoating and states plainly where the criticism is justified.

Mark at the end the two questions I would be worst prepared for if I only knew the material.
