I expect they will yes, but they might do this gradually, eg release a new screen assembly that is not compatible with the existing edge trim.
From internals they already have this with the AMD upgrade requiring you to update other internal parts. like wifi etc
The issue with solutions like this is the amount of power draw they require for the cooling potential. In non-battery powered ultra slim devices that have a low power draw. They may have a market, but they also cost a lot so that tends to be industrial applications that can absorb the cost and don’t have high thermal load.
That is why the demo is with a MacBook Air and they need to use three of them.
It is and has been used in industrial applications for a long time. Situations where you don’t want a spinning fan. But those are you say low power sustained cooling.
Yeah, that cooling solution actually ends up drawing more power than multiple high-performance, Apple Silicon CPU course
From the EU perspective iMessage does not even qualify as having enough regular users
It will be a lot of work to go correctly without leaking user info
Given a large part of the GSMA are gov agencies or carriers that are under gov pressure and subject to well established wire tapping requirements I would be very surprised if encryption is adopted. It was proposed during the original spec and refused and again more recently refused.
