Why again does people want clock time not to match solar time? It's far more sane to change the numbers on the schedule than to change the clock.
Making DST permanent "just" requires a singular change of legislation, and basically never switching the clocks back to "normal" time.
As has already been stated twice in a sibling discussion here, "changing an entire culture is hard", but I'm honestly interested in hearing your approach.
It's ridiculous to suggest that it's easider for every business update Google (and Yelp and everything else) twice yearly, and that everybody check that before they go anywhere. That is way more human labor than daylight savings.
In fact even my regular calendar app can support this but itself, it can notify me of changes in booked appointments automatically.
And even that's assuming you didn't already know the change in schedule because it was listed right there on the website.
Currently, clocks automatically change twice a year.
In your proposal, all schedules for businesses, schools, transport, etc need to be entered into multiple online services. Plus each person needs to use one of those services and tell it about all of their plans. Then they need to be notified by that service whenever anything changes, and when hours change in a way that's conflicting, they need to manually resolve that.
As an example, I was just talking with someone who has to pick up kids from two different schools; the route involves two different transit systems. All work meetings must be carefully scheduled to match, and there are inevitably errands that will involve zero, one, or two kids and getting to some place before they close. This is hard enough when hours are stable. Now imagine it with schools, transit systems, stores, work clients, and work vendors all potentially adjusting operating schedules 2 or more times per year.
Google Now can't do that, and probably won't before the Singularity.
