ARM is on the rise within the industry. It's not a trend only for Apple, but Apple might try to move more quickly than other players. My guess is that they'll try to evolve iPad, as an ARM-based portable device, before they look to bring MacBooks over to ARM. This will be a really strong signal that it's time to seriously start porting. Windows is also pushing more ARM support. As a result, some of the infrastructure e.g. Chromium and Electron is starting to get ARM support. I expect other tools, platforms, and frameworks to start getting ARM support, but it won't be quick, or uniform. This will speed up efforts across the industry. I think they really need to break with the past to get the huge battery life gains that are possible, and Intel/AMD don't have much to offer there. I don't think any of this will happen overnight, but Apple will look to move things quickly. I'm not sure it's the same situation that Apple found themselves in when they moved off PowerPC. That was an existential issue for their hardware. Now they are on the incumbent platform, so there is time to make a more considered transition. They have iPad as a place to experiment as long as they maintain the general usability and experience of that platform.
