It is a basic but at system level not obvious insight that you cannot ignore reality in how you educate your or anyone else's children. It is easy to be careful and conservative but for education to be useful you have to teach them about difficult topics early and thoroughly and both the substance and the methodology have to actually fit the reality these children can and do encounter every day and WILL eventually encounter once they leave the protected environment of school and parents.
You simply cannot teach a child to be a mature, employable, self-confident, independent, informed and sensible adult without the tools of the normal world. By all means, keep them away from tech completely and there are exactly two scenarios: 1) they sneak their way into getting access 2) they fall into an adult life they are not prepared for and will suffer for it.
You, as a parent or educator, mist face reality and discomfort yourself and engage with the world your children encounter. Teach them understanding and insight, not shame or fear.
