I am a 63 year old developer who is no longer “tech savvy”, because young people go out of their way to make things “different”, and then add insult to injury by claiming e.g. that their intent is to produce “surprise and delight”. I think you are right that this won’t change. So-called human interface designers design aesthetically pleasing toys for children, and insist that these are suitable for use as tools by everyone. Then when older people avoid buying their products, they console themselves with false beliefs that older people lack disposable income, and would buy a new cell phone etc. every year if they could. I save a lot of money because there’s no cell phone available that meets my basic requirements, so I make do with an elderly piece of junk that really isn’t much worse, by my standards, than this year’s top of the line.
In the unlikely event that the young designers cared about people unlike themselves, they’d at least write up the “obvious things everyone knows to try”, but since those things are obvious to them, and others their and your age, they do nothing of the kind.
I don’t believe anyone your age has ever used – or even seen – a good computer system. You are fine with 90% accuracy using your on-screen keyboard, complete with auto-correction resulting in what you didn’t intend to say. The idea of using a keyboard large enough for your fingers is outside your range of possibility, and you look forward to e.g. speech recognition (with even lesser accuracy) as an “improvement” over auto-corrected thumb-based pseudo-typing.
My hope is that as baby Boomers age a critical mass of older developers will eventually create tools for the rest of us, and let Apple and Google serve (and profit from) only those they design for. I don’t think this is likely, but if you’d like to be part of such a project, or know of anything already happening, I’d love to hear from you.
