It is a mandatory step in the development of the network and prosperity of bitcoin. So yes it won't be cancelled.
The title is misleading and since it suggest a eventual cancellation which is not true. A better title would be. Should the halving be cancelled?
That's what I think should happen and assume will happen ("unless miners want to kill bitcoin"). My logic is flawless, lol. If the halving is so beneficial for the "prosperity of bitcoin", why not cancel the miners reward altogether?
Fly me to the moon
because satoshi wanted that the reward was spread in a long time to permit adoption to take off, and to permit the efficiency to catch the reward itself
if it was done (the halving) every year, right now miners would be fucked basically
