Also I don't want to be a negative nancy or anything but a flight ceiling of 30km (100k feet) is very doubtful.

BTW The SR-71 had a max flight altitude of 85k feet and the pilots needed to wear full pressure suits.
The MiG-25 Foxbat achieved a maximum altitude of 123k feet with a zoom climb, it could not cruise at that altitude.

Everyone's talking about altitude and speed, but I think one major aspect not getting as much attention is stealth and the fact that J-36 would be the first supersonic tailless flying wing in the world (assuming SAC CHAD upfold tail at high speed)

If you look at old SR-72 calculations, radar detection range plays a big role in enemy engagement distance, tailless VLO design combined with high supersonic and high altitude means there is a very small to basically zero time-window between detection and J-36 leaving engagement envelope, i.e. the transit time between AAM/SAM launch and intercept is longer than time J-36 will spend within detection envelope.

If US NGAD was primarily subsonic VLO and they received intel on CHAD capabilities, I can see why they would want to pause the whole program, even if detection distances are the same, NGAD will basically have no window to intercept CHAD

With the advent of DEW on planes, the pilot is probably the softest target if the adversary comes within the engagement range. Dazzling or perhaps even blinding the pilot could be a very interesting possibility, even though the plane most likely will have autonomous capabilities - getting rid of the pilot could be a positive.
Perhaps PLA is expecting this from their adversaries or themselves are planning to field a pilot dazzler.
Would explain the tinted canopy as a pilot safety measure.

Can jet fighters fire off flares at supersonic speeds? If yes, then hard-kill munitions can be designed to be safely fired off as well, I believe. Also, if there is AI augmented flying, then during a evasive maneuver the AI can steer the plane into an optimal flight path for the Hard kill munition to intercept the incoming missile. From what I understand, most AA missiles follow the Proportional Guidance algorithm to intercept its target, so if you know where that missile is (and its heading and speed), you know where you are then you sort of know how that missile plans on killing you. At that point, AI can "lure" the incoming missile into a path what would be easier for the hard kill munition to get to given its limited fuel and kinematics. It is probably like solving some hairy partial differential equations.

Flares are really small so they easily have the structural strength for it to work, not comparable to a missile.

Yes, self defense missile is indeed quite feasible, there're open projects in the US and I bet a bunch of not so open projects in China working on such concept. I believe by 2030 those will be mature enough to deploy on 6th gen.

One thing about DEW is that they scatter once a sufficient distance is placed between the emitter and the target. Most lasers, for example, will not be much good after 5-10 km, especially shot horizontally where it has to go through the atmosphere for most of its travel. The scatter dissipates most of the energy. It is only good at short distance or vertically aimed so it quickly go outside of the atmosphere. You have to come awfully close to put the enemy pilot in harms way. If put on a plane, it is mainly used to take out incoming missiles. This will also only work if the plane itself is traveling at fairly high speed so there is sufficient time for the laser to burn through the electronics of the missile. Of course, if you get close and at the right angle, you can still harm the pilot, but long before you reach that distance, it would be much more effective to fire a missile. If you fire first, the no-scape zone means that most of the time, the enemy plane is going down.
