So transparent as to be invisible

I imagine one of the things our great-grandchildren will find quaintest about us is how we had all these different, function-specific devices. Their fridges will remind them of appointments and the trunks of their cars will, if need be, keep the groceries from thawing. The environment itself will be smart, rather than various function-specific nodes scattered through it. Genuinely ubiquitous computing spreads like warm Vaseline. Genuinely evolved interfaces are transparent, so transparent as to be invisible.
