The problem I see is that... I like having a phone and a laptop. Since we will never be able to fully participate in the modern world without them, unless society changes majorly, I would rather use the device I already have. An ideal forever computer would just be a very reliable modern laptop with a replaceable battery and a software suite that people somehow agree to maintain for the next few decades. It's possible now that we are at the good enough stage. Basic everyday tasks are no longer a challenge for CPUs, so in theory current laptops should be good till they break. If I were to actually want to build something myself, it would be a pi4 based cyberdeck powered by lithium titanate batteries. The author is a software guy, which is good, because most of the cool stuff he proposes can be done in software.
