Sometimes you buy a pi for one project start on it buy another for a different project, before you know it none are complete and you have ten Raspberry Pis lying around across various generations. ;)

Arduino hobbist, same issue.

Though I must admit to first noticing the trend decades before discovering Arduino when I looked at the stack of 289, 302, and 351W intake manifolds on my shelf and realised that I need the width of the 351W manifold but the fuel injection of the 302. Some things just never change.

I have different model Raspberry Pi's and I'm having a hard time justifying buying a 5... but if I can run LLMs off one or two... I just might. I guess what the next Raspberry Pi needs is a genuinely impressive GPU that COULD run small AI models, so people will start cracking at it.
