>>63864848This, piezoelectric actuators that produce small bubbles/bumps on the control surfaces to disrupt airflow like flap/slat spoilers do; jet or forced air slots and holes, Continuous Moldline Technology (CMT) similar to what you posted; and fluidic TVC are all possible technologies that are within the realm of reality as to what type of control surface technologies that could be matured enough to be on the NGAD (Air Force F-X) and the NGAD (Navy F/A-XX).
They've been working on these technologies since the early-mid 90s, and some are at a Tech Readiness (TR) level that they're able to be reliable, cheap-ish, and easy enough to mass produce manufacturing wise.
China even stole the CMT tech from NASA/Boeing for the J-36 and J-50, and copied their designs from a mid 90s study done by McDonnell Douglas (Boeing) for NASA.
If you're wondering where China got the design for the J-36 from, look no further than a 1994 NASA study done by McDonnell Douglas.

Same with their J-50, though, they added the all-moving tips from the NASA/USAF Innovative Control Effectors (ICE) study done by Lockheed Martin.
China stole the Continuous Moldline Technology (CMT) tech NASA developed for the Fighter Lift and Control (FLAC)/Subsonic High Alpha Research Concept (SHARC) and slapped it on the drag rudders claiming they invented it, it's revolutionary, and not for NASA in the late 1990s. KEK
Even the Chinsects know they stole it: https://www.zhangqiaokeyan.com/ntis-science-report_nasa_thesis/02071203239.html
