この動画の主要な問題提起は、英語表現「so as to」のネイティブスピーカーによる実際の使用状況にあります。

・まず、「〜するために」という意味の「so as to」が、日常会話でどの程度使われるのかという疑問が提示されています。
・この表現は英検などで見かける一方で、ネイティブにはあまり使われない、または古く感じる場合があると指摘されています。
・また、否定形の「so as not to」（〜しないために）についても、使用頻度や適切な形式に関する不明瞭さが問題として挙げられています。
・さらに、「in order to」も硬い表現とされ、否定形では「in order not to」の方が口語で使われることもあるなど、代替表現との比較も焦点となっています。
・したがって、この動画は「so as to」系列の表現が、ネイティブにとって自然な英語表現であるのかを、個人の経験に基づいた見解として考察しています。
