Not only is it generally harmless when eaten, it is in fact allowed to be added to food in up to 5% concentrations in Europe, 2% in the US. The FDA lists it as “Generally Recognised as Safe”. https://en.m.wikipedia.org/wiki/Silica_gel#Uses
I suspect that the whole “Do Not Eat” is partly because the Silica Gel in the little bags is not made to food safe standards, but that’s just speculation on my part
