Hopefully, the development cycle could be sped up.

He says WS-10 is a copy of AL-31.

it's obvious he is a Quack expert. Instant credibility loss.

He does know a lot of stuff and certainly is an engineer who's worked in these fields. The issue with his content on China though is that he's a lazy expert and doesn't bother learning anything about Chinese things, preferring to simplify everything into "it's a copy of something".

The fact that China is behind western military aviation doesn't help China's case since everything is at least based off something else if nothing more than conceptually based off.

On top of this, he's also extremely politically motivated. I mean he talks up the Tejas and really makes some effort to placate Indians. The Tejas, even for 4th gen fighter design, has absolutely no aerodynamic sophistication but he finds a way to talk it up and reduces Chinese designs to "well it's between Soviet and American designs"... like the Tejas isn't a totally French design.

He seems to have some proper experience with regards to aeronautical engineering like software, avionics, or airframe design.
But engines are the domain of mechanical and materials engineers not aeronautical ones.
I also agree that he is lazy with regards to Chinese airplane analysis. Not that we can blame him much since there is little information on them in the West except for Deino's books.
About Tejas, is probably just because there is a huge amount of Indians on YouTube. He has to pander to the audience a bit. Chinese don't use YouTube nearly as much. It is banned inside China anyway.
