The problem is that you can't put a blanket statement about all aluminium frames. Material fatigue life is finite, but you can't really have any idea how long without fully understanding the design and knowing the real loading (use case, rider weight, power, style, etc.). E.g. a lightweight racing frame might have a 'lifespan' of 3 years and a heavy-duty commuter or MTB might last decades. I still regularly get around on a 20 year old aluminium frame with no signs of failing yet, including regular stops at the pump n jump track... I wonder how many steel frames have rusted out in that time?
