Q. Is this really as harmful as you think?
A. Go to your parents house, your grandparents house etc and look at their Windows PC, look at the installed software in the past year, and try to use the device. Run some antivirus scans. There’s no way this implementation doesn’t end in tears — there’s a reason there’s a trillion dollar security industry, and that most problems revolve around malware and endpoints.
Even supposing I didn’t care about the security implications of this, why on earth would I want this functionality? I can barely keep up with all my activities in the present moment, let alone the past. It’s like a morbid and pathological unification of nostalgia and hoarding.
