The 20 year old me would have been so excited about something like this. The 39-year old (ok 40 next month) is more reserved. It is not that I don't think this will be adapted but more like : What needs to happen (government, civic groups whatever economic forces) for companies to adapt this? It's going to be a slow burn for sure if this needs to work at a global scale but the impetus should begin with incentives, sadly.
