You didn't learn much.
Aluminum is a 'real presence in the bike industry'. I have owned several. Zinn nailed the dynamic relative to Fatigue life...yield strength of Al relative to SN curve and number of cycles. Engineers understand this. I am an engineer. Designs are created based upon material properties. An Aluminum frame could weigh 650g like an Emonda SLR carbon frame. It would likely fail. Yield strength matters. SN curve matters. No. of cycles of loading matters. Engineers understand these things. Its why airplanes are deemed safe by the FAA.
You need to get over 'yourself'. The industry ignores you.
