On the contrary, it points out that action potentials are dependent on the interaction of multiple ions flowing in different directions (which mathematically is a system of partial differential equations that varies from neuron to neuron), and is highly dependent on the history of the neuron. No system designed to simulate real neurons uses a sum, the simplest model is an integrate and fire model, which reduces this system of differential equations to a single differential equation and a tacked-on kludge for the actual spikes.

But that article only provides an extremely simplified look at just one factor. There is a lot more going on besides that. Once you finish actually reading the article you linked to, I suggest you read up on low-threshold-activated potassium channels, backwards-propagating action potentials, volume transmission, bursting behavior, onset neurons, and dendritic spines. And that is just the tip of the iceberg, that is a lot more going on besides that.

Overall, it might be better not to presume to lecture a neuroscientist about the most basic aspects of neuroscience.
