I think the Borg will assimilate all of us - the cloud already has my gmail, my photos (some of them), all the stuff my banks know about me and so on. And at work - that’s one ginormous cloud right there. There are some decisions and individual will be able to make about local vs. cloud but technological trends, once in place, are hard to resist forever. Floppy disks, VHS, dial phones, modems etc. etc. are all testament to that.
I can only say that we can continue to be diligent about our own privacy if we choose to. I got off of gMail recently. Not that my ISP email is any better, but they’re a smaller outfit and likely not going to be targeted for a large-scale hack attack. My bank, same sort of thing.
Yes, there will be assimilation, but we can still retain our individuality if we choose what goes into that cloud. I run a small SMTP server out of my home for private communications with my family, and I keep everything encrypted, if possible. I minimize my time on the phone and with texting. I’d like to think I’m as off the grid as I can be without losing a few conveniences of daily living.
