No surprise that supply and demand have the same gross characteristics. But the devil is in the details or in this case in the accelerations and decelerations of the demand that create an imbalance between supply and demand. ...Or to be mathematical about it - demand is the independent variable to which the supply reacts (via my "mechanism"). No one would advocate adding more supply in order to boost weak demand. ...Yes the bust is triggered by "oversupply" but what actually happens is that a capacity boom is triggered by accelerating demand. And then that demand decelerates but the time lag effect keeps the capacity increasing long after the demand growth has slacked off. <<I think the magnitude of the demand curve will get past the the unique boom/bust of the bubble and will return to even stronger growth rates.>> ...?? I'm not sure quite what you are trying to say here. But yes - eventually the hypergrowth will dissipate as Moore's curve flattens out. At we will be left with the more tepid boom-bust cycles of the auto industry. ...But I still contend that 1) the shrinks and Moore's law are still trundling on and 2) we still have the 300mm/automation transition to go through. So, no, I don't believe that we are at the end of the road...Yet. <<the bubble of '98-'00 was not a typical semiconductor cycle>>. ...No cycle is ever typical. But yes, the last one felt like a perfect storm. On the other hand the previous cycle felt like the worst thing possible ('89 - 92). Economy in the dumps, massive layoffs, jobless recovery, Iraq war, the "PC era" was "over". ...Who's to say that the next boom bust won't be even more severe? <<...by influencing the supply (capacity) dynamic to be more incremental.>> It is possible that the foundries will form some kind of a cartel (ala OPEC) in order to divide up market share and boost prices by limiting supply. But nothing like that has happened yet. ...You still have a significant number of players (10+) who are all vying to gain market share. Which means that when the demand surpasses capacity they will all rush to be the first to bring new, lower cost capacity online. Time will tell. Sooner or later this insanity must come to an end. Either the demand will abate (the end of Moore's law) or the supply(ers) will game the system to give themselves controllable profits.
