Very true. Perhaps my statement which continued on beyond what you quoted didn't make it clear, but I did point out what you said: "You've got brakes, but you're without any of the assistance that the car normally provides" as well as stating later that you've got "naught but your unaided foot on the brake peddle" both of which were intended to say that it's pretty hard to brake in most cars these days without power brakes.
I don't know how the Cybertruck breaks down on the easy <-> difficult manual braking spectrum, but I imagine that given the high gross vehicle weight and large wheels, it probably steers more towards the difficult end of the spectrum than the easy. Such a dumpster fire of a vehicle.
