I completely understand why someone would want to erase certain memories, and depending on the particular memory, maybe it would be beneficial for some situations. But I do think there is a value to working through life's tragedies. Through the worst parts of life, I have found that there is great opportunity for growth and love for ourselves and for others. I am concerned this technology takes "ignorance is bliss" a little too close to heart. I just know that I wouldn't be as strong as I am now if I couldn't remember the awful things that have happened to me. They have shaped who I have become. Yes, in bad ways... but also in good ways.
