<p>"Multi-user"라는 이름이 붙은 건 유닉스의 역사 때문입니다. 유닉스는 원래 <strong>메인프레임에 여러 사람이 터미널로 동시 접속</strong>하던 시대에 설계됐습니다. 그래서:</p>
<ul>
<li><strong>Single-user</strong> = 관리자 혼자만, 최소 환경</li>
<li><strong>Multi-user</strong> = 여러 사람이 동시에 쓸 수 있는 완전한 환경</li>
</ul>
<p>오늘날 개인 PC에서 혼자 쓰더라도 <strong>"Multi-user 모드"가 정상 운영 모드</strong>입니다. Windows의 Guest 계정과는 전혀 관계없는 개념입니다.</p>

- 현실은 인간의 연산으로 완전히 파악할 수 없는 복잡계. 주어진 상황과 능력으로 할 수 있는 최선의 적응은 단순함과 꾸준함.

  - 파산을 면하는 선에서 여러가지를 해보고 자신에게 맞는 걸 위주로 꾸준히. 그를 위해 단순, 편안, 쾌적함이 필요.
