Nice GIF. I understand the earth field very well being a geophysicist who has done many magnetic surveys of the earth. As for whether it is not an issue remains to be seen. The poles may not just shift, but instead they could go into an intermediary transitional phase where there are no well defined poles. This has been recorded in volcanic rocks many times. But, there is probably nothing to lose any sleep over. Except telecommunications and power grids may be affected if the field fails and lets in more cosmic radiation:
Movement of North Magnetic Pole is accelerating
