EXPERIENTIAL FUTURIST,실험적미래주의 - AI, 블랙미러와 소셜딜레마로 보는 미래 디자인 by 장익환

  • 나도 무언가 미래지향적인 새로운 것을 만들고자 하였는데 난 몇 가지 내 머릿속에 특히 엔지니어로써의 그 ‘툴’은 알고있지만 다른것은 몰랐으니 이건 너무나도 당연하게 결과물은 이게 뭔지 도통 알 수없는 상황이 된 것이다
  • 중고등학교때 내가 홈페이지 만드는 것을 좋아했던 이유는 개인홈페이지를 통해서 나만의 그 디자인을 만들면서 꾸미는 것이 좋았었고 각각의 홈페이지마다 디자인에 대한 의미도 있었다
  • 그간 나는 데이터와 시각화를 통해 다른 시각을 낼 수 있는 방법에 대해서 생각했었는데 이를 유라임을 엔지니어링 적 이외에 어떻게 더 만들고 나아가야 할지에 대해 감을 잡을 수 없었다
