GigaZ precisions would require a much more accurate determination than available today. A combination of the virtues of current methods may help to achieve this goal.3 pages, Talk presented at the Workshop "The Future of High Energy Physics" (Snowmass 2001)High Energy Physics - PhenomenologyDeterminations of alpha(M_Z): Comparison and Prospectstext
