Yea when I was still on Wattpad, I made a joke that if you had a political compass as far as what aspects were hard scifi and what parts where soft science fiction, I'd say my work was soft science fiction that focuses on accurate portrayls of cryptography and hacker culture and programming.
But otherwise, has more in common with 12 Monkeys or Elfen Lied than anything by Heinlien.
I do believe Scifi hardness is more a hardness compass rather than a sliding scale though. I do hard programming, but soft in every other respect.
