Look, I don't want to rain on your parade. It's not going to happen the way you see it. Let me explain:
There are currently 8,500 Chinese workers in Pakistan working on the CPEC. 8,000 Pakistani soldiers are protecting them. Any further work on the CPEC will require Pakistan to devote substantially more to security. Once the infrastructure is up, who will use it? The manufacturing and service sector jobs will not materialize, because people have this annoying tendency to stay away from places where they are likely to get killed. You would too; just that you can act smart from behind a computer screen.
Pakistan can at best hope that the army will be able to protect the route from Gwadar to the Chinese border. Best case scenario is that Gwadar will become a fully-functional port with a heavily guarded area around it with some economic activities. The Chinese have not even explained where the enire funding will come from; because they themselves are treading cautiously.
What is going to happen is that a year down the line, you will be spewing bile at Nawaz Sharif, calling him a traitor for not being able to deliver anything substantial on CPEC. You will conveniently skip the part that the project did not collapse due to corruption (although that too will play its part) alone, but due to the unsustainable security scenario in Pakistan. You will once again blame your civilian government for something created by the Army/ISI nexus.
But of course, don't worry, you will be able to get your hands on some more cash, it will make a few politicians and sub-contractors richer. And that will be the end of that.
