it is better for educated ppl to stick to the merits & discussion of the topic
Re-read your own title, the question is
why not?, and I did answer your topic's querry.
Why don't you show some merit by convincing deliberations, as to why should we.
It's a 1936 concept, so yeah, it's an old design.
Example would be, if Quaid's car is still driveable today, doesn't mean it's a new and improved design.
The only X-29 still under experimentation is now with NASA, not with USAF anylonger.
Their criterion is not warfare, but to design a space vehicle, on rentry without power, it glides faster.
Again, they have billions of Dollars of yearly budget, to see all the pros & con's, and then work on offsetting the cons.
Their project funding is based on gaining knowledge, and that is exactly what they are doing, and printing all that as text book material.
Forward swept wings will be in case studies in almost all Aerodynamics course materials, it's been there even before my dad was born, how can it be something wow?
I've given you the synopsis in post 7, it's your call to study it, or keep watching u-tube videos, not my loss.
This illustration shows the reverse airflow on forward swept wings vs. the airflow on the swept-back wings. On the forward swept wing, the air tended to flow inward toward the root of the wing rather than outward toward the wing tip as on the swept-back wing.

The lower illustration shows how the canards on forward swept-wing X-29 will share the lifting load and reduce drag as compared to a conventional aircraft in the upper diagram.
