Setting up an industry framework takes time and if you are building something which requires most modern techs its gonna take more time and to add to that if its done in a country that had no basic high tech industrial setup and being an agrarian economy under the international sanctions.
From outside people can complain for 1000s of things, but to drive from inside it takes lot of courage to meet all the obstacles. Some obstacles where met with best solutions and in others there could have been hit and trial or failures. None the less entire exercise has built a very fertile base for upcoming high tech industries. It has prepared the right set of ground to run and jump ahead.
