I saw the thread about how the AI matrix diagonal is used to get SE, but what is the layman interpretation? Thanks

Any parameter is estimated with error. In classical statistics, the point estimate of a parameter is regarded as a random variable following a distribution, e.g. normal distribution if the sample size is large. SE is just the standard deviation of this distribution, measuring the accuracy of the an estimate.
