comment Is classical electromagnetism a dead research field?
Isn't this so much a problem as an indication that the theory is incomplete and has to be replaced with quantum electrodynamics, which solves both problems? The self-reaction is subsumed into corrections to the electron propagator and the "reaction force" can be handled in the background field mechanism.

comment Are the $10^{500}$ different string theories being whittled down?
10^500 is a conservative estimate, the number might be much larger. But even 10^500 is beyond anything imaginable, the whole universe does not contain enough atoms to store 10^500 integers for example, let alone the parameters for 10^500 string models. Also each of those backgrounds potentially has a number of continuous parameters.

comment Does the mass point move?
Alfred Centauri, yes but it is equally impossible to exactly generate any kind of force, so to me this is as unrealistic as a sudden violent onset of a force at t=0, modelled by a step function. Realistically you will only be able to approximate it by forces that have some non zero time derivative at t=0.
