Pilots no longer wear helmet, goggles, and a
silk scarf.

Why not? Those things are still there, and still available to us.
I've worn the helmet, goggles, and silk scarf, and I've looped and
rolled an open cockpit biplane over the countryside.

Me too! But not nearly often enough. Once in awhile, in a friend's
Starduster.

But I learned to do that in the navy, in an SNJ, more than 50 years
ago. I have a fair number of flying friends, younger than I, and not
one of them has ever rolled or looped or spun an airplane, or flown in
an open cocpit, or worn helmet and goggles; and only one has ever
flown a taildragger (he bought a C-140, a couple of years ago.)
