What if you all been blinded by your silly minds?   Imagine y2k?   How was it fixed?   Remember ?   I do.   They wrote code to move the dates around.  So year 00 became 2000 and they did the fix as in 2020 will be the year that all old system should been changed.   Oops   if it ain't broken dont fix it.   Did they forget?   So 2020 was y2k20 and that is why airplanes had to be grounded. Stick market had to be halted and big money transfers un banks had to be cut down.  Now new mainframes had to be built and bought and installed.   Humm now shortage in silicon?    Why well many big mainframes had to be changed.  So cut the sales of the retailers.   Oops.   Did I spill the beans?
