These devices work, they were just not designed to do this particular job...they cannot discriminate between variants at all.
And if you crank up the cycles enough it will say anything tests positive. If you use a reasonable setting the device can tell if you have ‘something’
Plus the added safety measure of not keeping track of what PCR cycle they are running to get positives. It helps when they want many CASES CASES CASES. Today we reached another GRIM MILESTONE.... Looking back, the excess deaths will be almost a blip, not a big bump.
