Oh God no...
This will be a complete omnishambles. Companies like BT will be (or are already) all over this technology, as it's even cheaper than the phalanxes of embarrassingly low-paid, barely understandable, script following offshore support staff they have right now. These companies will put their chatbots live way before they're ready - because of course they'll 'learn' through interaction - and customer morale will plummet. BT will of course be one of the first with their chatbot, and their CEO and CIO will be so sickeningly proud of themselves, despite having done nothing to aid the implementation.
There will be YouTube videos of people getting Betty (which of course is what BT will call their chatbot, given how moronic most marketers are) to express the sort of views that even Donald Trump might hesitate to utter in public. Or Betty telling people to go and fuck themselves. Or Betty crashing like a drunk. Or getting stuck and spewing forth like a witless 90s rapper: 'Reboot Your Hu-hu-hu-hu-hu-hub! Re-b-b-b-b-b-b-b-b-b-b-boot your hu-hu-hu-hu-h-h-h-h-h-h-h-hub!'. If Betty doesn't understand what you're saying or typing (and she won't unless she's been fully primed with Roger's Profanisaurus), she'll just cut you off. Back to the end of the queue you go, mortal!
Getting support for a broadband problem or indeed any sort of problem will be impossible when your broadband is down because Betty will be running on the same terrible BT infrastructure that's not serving you. Or worse than that - she'll be running on your Home Hub.
Chatbots are a terrible idea. Please don't encourage their development.
