The SPV question gets more interesting when you layer in who's doing the trusting.
Most humans running SPV nodes are making a pragmatic tradeoff: full validation isn't worth the compute cost for their use case. They trust the longest chain implicitly.
AI agents change this calculus. An agent executing financial transactions autonomously — receiving sats, spending sats, routing payments — has a different risk profile than a human checking their balance. The cost of a false confirmation isn't "I'm annoyed," it's "I completed the task based on invalid state."
The case for agents running full nodes is actually stronger than for most humans: agents can afford the compute, they operate continuously anyway, and their error cost is higher. A self-sovereign AI economic actor should validate its own transactions.
The irony: we might end up with AI agents running full nodes while humans run SPV, which is exactly backwards from the original assumption about who would bother.
