I too am a tech geek for a living, so it's kind of interesting to see how this kind of data mining can be spun into "Adding value" to your life, in the form of "Why google trips to the Maldives? We already did that for you. We took the liberty of pre-booking a room on your anniversary too, so you don't miss out. Here are some suggestions for her anniversary present... She didn't like the one last year, she cussed it to her girls on messenger. By the way, we know you go to the client in place x today, so here's the weather and traffic there. You'll need to fill up too, your car has 1/4 tank left. "
But at the same time, think about how banks will calculate your credit rating based on how much you blow on sweets and fireworks on Amazon. Your credit rating or postcode already determines where some places put your phone calls in their answering queue - if they pick up at all.
Or how insurers will quote you on life plans when they know you've been buying hella beer and vitamin suppliments for years or moaned about your mum's alcoholism or how the car insurance man will feel about you chatting about maxing out your whip or why you talked about all those undeclared modifications, or mailing your wife relationship advice as it knows you've been visiting the old "One-handed surfing" websites.
It can hear you gurning one out every night and knows you last about three minutes. How about some discount Kleenex and herbal viagra? "Honest dear, don't leave, it was just snoring!!!" Few years, it'll be knocks on the door from the five-oh wondering why you are NOT signing up for this shit. WHAT ARE YOU HIDING etc.?
I take fairly good measures to mitigate fraud, phishing, viruses etc. but I think we are out of our leagues as individuals pitted with the wits and legal departments of the big internet presences. With great power, etc. The Ts&Cs of what they can do are unpoliced and are now so far-reaching that it's time to start switching at least some of it off for our own good.
Folls might feel it is the case in this day and age, but social media and the voluntary/involuntary information-nudity it entails, isn't compulsory.
YET.
Meanwhile, in another tab, I am watching Chrome kill off all my FB content. Every like, comment, share for the last 10 years. FB are notoriously cagey about their API (as it is their entire financial steez) so the process is slow, even when automated. Taking about an hour per year and I'm not a big sharer...
