I think you should keep your uninformed ageist ideas to yourself. Who are you to say that we're mostly of an age on here that trusts cash and distrusts technology? I'm of the same generation as Tim Berners-Lee, the inventor of the HTML protocol that led to the World-Wide Web. As a consultant Software Engineer, I have (I hope) fairly balanced and informed ideas about the issues you are talking about. I see no advantage in going cashless for punting transactions in the foreseeable future. Something like PayPal might be an option in the future, but it is unlikely to happen: the privacy we want as punters will not be acceptable to the law enforcement agencies. The mythical entrepreneur you envisage will have an impossibly hard sell.
Cheers!
Wind your neck in, matey! I stand by everything I wrote. Of course there are exceptions, that is why I said "mostly". And I said a
healthy distrust - that is not any kind of an insult whatsoever. And even then only a distrust of "technology for it's own sake". You seem to bloody well agree with me in the rest of what you have written.
Of course a replacement for cash would only be accepted if it gave the benefits of cash. Like I said it has to be
anonymous - it would have to be demonstrably so. I really don't know why you thought you were adding anything with this response, to be honest. I've worked in software development myself for almost 40 years, much of it associated with authentication and encryption so I think I have gained some familiarity with the damn subject. And I've also gained a suspicion of those who add "consultant" to their job title that has just been reinforced...
But cheers!
