lol so Imma be that guy...I know that looks dangerous, but as someone who worked for years as a third generation contractor and someone very conscious of safety, I can tell you it's much safer than it looks. As weight is put on the ladder it's forced against the ledge and against the rails, and the top is forced against the wall, so it's virtually impossible for it to move. My problem would be convincing myself to not look down lol
