I heard two quotes, one from Alain Connes and an other one from Orlov. Alain Connes was talking about noncommutative geometry and he said the following: **" a noncommutative algebra creates its own internal time "** In a talk by Orlov about Mirror symmetry, he was asked if he considers the monoidal structure on the derived category of a scheme. Orlov said that "**the monoidal structure is not natural in this context and we should not base our theory on this structure** " he added "**The tensor product is a NATURAL structure to consider in the category of Motives**" I will be happy if someone can put some enlightenment to what Connes and Orlov meant (if the quotations above make sense ) ?
