The article reads like a puff.

Heat is generated in IC circuits not just by the resistance to the
flow of electricity but by switching losses. Heat is generated every
time a bit switches from 0 to 1 (or vice versa). Even if there are no
ohmic losses, switching losses remain.


The only cause of heat is current through resistance. This happens
*during* the transistion of 0-1 and vice-versa in switching applications.

Because during the transition from open to closed (or vice versa), there
is current flow through a resistance. A switch circuit does not go from
open to closed (or vice versa) in no time at all; there is a very (very,
very) short time when the switch is a (variable) resistor.
