Spiking networks also lend themselves nicely to some elegant learning rules, such as STDP. Being able to perform unsupervised learning at the grain of each action potential is really important in my mind. This gives you all kinds of ridiculous capabilities, most notably being the ability to train the model while it's live in production (learning & use are effectively the same thing).
These networks also provide a sort of deterministic, event-over-time tracing that is absent in the models we see today. In my prototypes, the action potentials are serialized through a ring buffer, and then logged off to a database in order to perfectly replay any given session. This information can be used to bootstrap the model (offline training) by "rewinding" things very precisely and otherwise branching time to your advantage.
The #1 reason I've been thinking about this path is that low-latency, serialized, real-time signal processing is somewhat antagonistic to GPU acceleration. I fear there is an appreciable % of AI research predicated on some notion that you need at least 1 beefy GPU to start doing your work. Looking at fintech, we are able to discover some very interesting pieces of technology which can service streams of events at unbelievable rates and scales - and they only depend on a handful of CPU cores in order to achieve this.
Right now, I think A Time Domain Is All You Need. I was inspired to go outside of the box by this paper: https://arxiv.org/abs/2304.06035. Part 11 got me thinking.
