Authors’ Pseudo-Conclusion

  1. Dear 'Time Machine1' Research Group: We appreciate the distinction between changing the past (impossible) and affecting the past (possible). However, this simply reinforces our initial impression: your project has no practical value.
  2. If in order to travel to the past one has to have been there already, and if one can only do what has already been done, then a quoi bon l'effort? Why should we invest in a 'Time Machine2' at all? We are afraid that our decision is now final.
