[Community] Any thoughts on the "Phonebloks" project?

There are numerous threads on Reddit that explain very well why this is
not feasible [1,2,many]
The (imho) most important ones in short:
* Mechanical modularity increases size and cost, makes it harder to create
a beautiful phone, and is not in the manufacturer's commercial interests.
Therefore, it would be hard to find companies/customers to build/buy this.
* Many current components are highly integrated - SoCs, sensor ICs,
Display/Touchscreen, etc. Making these modular would require development
of many new components (and would increase size, cost, power consumption).
* The concept assumes that all components use a common communication
backplane. This is not feasible, as a variety of voltages and
communication protocols are in use in a typical phone (I2C, SPI, UART,
USB, various display protocols, etc.). Many components need very short
connections to the CPU/GPU/whatever without crossing other PCB traces. It
is not realistic to make this work with a generic communication backplane.
Proper heat dissipation for CPU/GPU is another problem.
In summary, while it is certainly feasible to build a modular phone (look
at David Mellis' DIY cellphone ), doing so for current hardware would
involve major engineering effort (== design and manufacture dozens of new
chips) and would result in less stable, more expensive, and less beautiful
phones requiring more power.
