are we sure the RAM market will stop being insane in a year or two or could this be the new norm?
1. Yes, it's the new normal, then production capacity will be increased and prices fall.
2. No, it's not the new normal, the bubble pops and component prices come crashing down when buyers default etc.
Option 2 has been the normal outcome of these situations so far. But sure, questions remains how long all of this will take.
In that case prices will continue to rise (among other things).
