The problem will solve itself. The reward over time is only as low as many miners take part in the mining game. Lower the reward and many miners will switch off their unprofitable miners. Which means the remaining rewards will be split through the remaining miners, which means they will earn more.
I don't particularly disagree with the said. In fact, I already mentioned something to that tune somewhere in the thread earlier. There are two major issues with this, though. First, this problem is apparently the flaw in design (an
arbitrarily set number), at least, the way it is set up to work (if anyone begs to differ, think about how non-optimal (or, better, disruptive) the halving is/will be). Second, the disrupture in Bitcoin operation may be fatal to it, meaning it may never fully recover from
this halving...
