3 computing events

Three ?computing? events are happening: 1) The i-Pad was introduced by S. Jobs 8 yrs. ago and defined a ?new? computing paradigm for the masses. The reason I mention this event is because a young friend(20 yrs. old) said ?That?s ancient computing!? What is one to make of classic-computing then? 2) Bitcoin mining ? The energy usage is extreme because of GPUs. Was 16-bit computer era, employing the 80287, such an energy hog? 3) INTEL doesn?t seem to have been hurt by Meltdown & Specture financially- speaking. Had excellent earnings and profits for the last quarter but ?may? change this quarter. However, INTEL marches on going from 4004 to 7980XE. AMD was/in the picture but financially-wise? Happy computing all! Murray J
