Id say it’s experience by the programmer that is at fault, and that’s due to this bootcamp nature of learning programming.

You are getting downvoted, because this is factually proven wrong by studies and internal analysis of several huge companies (e.g. google/android and microsoft). A huge number of exploitable bugs are preventable using memory safe languages, nowadays even without performance costs (Rust).

Apart from that your point is orthogonal to the point of the post. You can have better trained coders and have them use better, safer technologies.

We could also just train every driver more thoroughly including mental training and meditation to make sure they are more calm and focussed when driving and we maybe wouldn't need seatbelts anymore. But:

1. Is that a realistic scenario?
2. Why not use seatbelts anyway, so there's a higher chance of not dying if some driver didn't sleep well that day?
