No doubt steel has it’s place; but largely it is under those with a nostalgic interest, not one of optimized performance. Bikes are tools for most in the performance market.
Really? Because a conventional steel frame is more aerodynamic (and, I would argue, higher performance as a result) that the overwhelming majority of road frames currently available, and quite a few TT bikes as well.
I think bikes are actually fashion accessories for most in the performance market.
