No, I truly believe that having a way for everyone to communicate for free, privately, and anywhere is just so great. This level of communication enables so many possibilities for people that couldn't been done so simply oterhwise. I live in Hong Kong and do not know a single person not using whatsapp. It helps everyone.
Although I'm a huge fan of space exploration as well, I still think letting people to communicate easily is more valuable for our day to day lives.
