Even better is only 80 years for aluminum, the third most common mineral in Earth's crust, constituting 8% of its weight. What an absurd alarmism.

Even if we can't get more. It's not like we're using it in a nuclear reaction that turns aluminium into something else. The aluminium is still there.

Not to mention how incredibly recyclable it is. In the US alone aluminum is made from scrap >30% percent of the time [1].

And after 4 generations, less than 1% of the original material remains.
percent remaining = 100 * (r^generations))
Even at 90% recovery, over 90% of the original material is lost after 22 generations. The highest recycling rate of any material in the US is lead (mostly from auto batteries). The USGS reports that rate as ~70%, though this may be the amount of recycled material in new production.
