Are Frameworks even upgradeable enough to enable the same kind of upgrading in the typical upgrade window as one would get buying a new machine? This means replacing nearly everything except the chassis, keyboard, and screen.

My current 128gb AI 300 started as a 16 GB 12th gen Intel. Unrelated, I also upgraded to the higher resolution screen.

For me anyway, the answer is "yes".

Still better than perma-nonce.

This is maybe down to using the same cognitive pathways to navigate SW that we use to navigate the real world: way points en route to a destination. Whereas those with more understanding of the system can deploy other methods that are a more direct fit to that structure. The problem is, then, that if you change the terrain (e.g. new os) you also need to change the map/route in the heads of all those users without system knowledge. Even some of those with system knowledge might STILL preferentially deploy their innate navigation cognition.

Most, and I mean scientists and not, don't seem to understand that ALL modelling is curve fitting. Applying maths equations to real data is always thus.
