The HoTT objects, such as the circles and the spheres expressed as
HITs, may be interpreted in many different models, some of which will
give "old objects" and other "new ones". So at least at this level it
is a bit pointless to discuss things in absolute terms. The HoTT
proofs are *also* about the usual spheres.

With kind regards,

Andrej
