Eventually all the old-timers (i.e. those who have calculators with real buttons, not touch-screens) will retire, resign, or just give up in disgust, and I'll be able to charge extortionate fees for doing niche or bespoke work, such as long division.<br /><br />They need to read:<br />http://dspace.mit.edu/bitstream/handle/1721.1/97690/MIT-CSAIL-TR-2015-026.pdf?sequence=8<br /><br />Co-authored by Whitfield Diffie (Co-inventor of public key encryption), and Ronald L.
