Problem with Russia is they don t have electronic technologies, they don t know anything about software and operating systems, they are outdated.
Probably SU-35 and pak fa are the last russian export batches we are going to see, Russia is far from leading future technologies. You only have to see their pilot cabins, they don t know what digilization is, and all their sensors are analogic and outdated...Their model of intelligence must be biased and in diapers right now...they don t know what IA is.
Russia must give all their know how to iran in order to catch up, because iranians are excellent researchers and will research in all fields, iranians are eager to know all and do things in their house. Hopefully, Russia moves right, gives all know how they have now to iranians and stop playing stupid games for once.
Time is important.
