How technical is too technical?

Hi Jordan! I'm currently applying to MSCS programs and had a few questions on how technical my SOP should be.

1. Should I treat the admissions committee as laymen and keep things as simple as possible?

2. Do professors go through SOPs often? If they do, would I benefit from adding more technical detail?

3. Are there any areas where I should not sacrifice technical detail? For example, if you're elaborating on your research goals shouldn't you be as specific as possible?

Thanks in advance!
