Different process but a similar result. It causes thinning in part of the filament which then has greater dissipation and earlier failure.

Atoms don’t move either. Atoms get excited under heat or pressure but they don’t move. Only the valance elections drift between the atoms. At that what I learned in school.

Not true. That is what happens with regular current flow but electromigration is different. The actual atoms move.
