I have no connection to the industry within Pakistan, but anyone with basic knowledge of how this stuff works, then taking a look at Pakistan's economy size, the level of STEM graduates it produces, university R&D, and observing its missile program, perhaps talking to a few people who know some stuff internally, and how the society generally functions (careless, ignorant, low effort, believe their old systems will work fine decades later) will be able to have a good estimation of where it stands.
And then a fanboy comes along and will tell you about Pakistan's super capabilities in every domain which there's no evidence of, in fact there is evidence of the opposite, and tells you to just believe it. Obviously such a person shouldn't be taken seriously.
