The steel is only temporary. Of course one could argue any temporary structure should be up to scratch, but anyway it's not the final solution. He's building a tunnel within the steel structure and then filling the void with concrete.

Well, that's what I understood from the last vid. But until then he is standing under structure that is definitely not safe. The trouble with these kinds of things is that everything looks fine until it doesn't. The way engineering solves these problems is through body of knowledge and experience in understanding of material properties and interaction of forces of both ground and the structure. The ground my start slipping slowly or it might decide to give in one go. It might happen after a particularly heavy rain or for no apparent reason at all. Unfortunately, I am not an expert in the type of ground he is facing. So either he is working with professionals (and hiding it to make the video more entertaining and in spirit of his other projects) or he isn't. In either case I think it is bad because it promotes the idea other people can do the same. Which is extremely dangerous in irresponsible to do on your own.

  what if i said i think its dangerous that you operate a car, and worse, you encourage others to drive cars when they see you driving a car.

    I find it quite refreshing that there aren't warnings not to try this at home. If people want to have a go, they will whether told to or not.

    Engineers go through training to build safe tunnels and drivers go through training and exams to drive the car safely. Maybe you have heard, there are even rules that aim to making driving safer. Both tunnel collapses and car crashes happen, but but less because we have regulation to prevent most of the carnage. The correct analogy would be showing on youtube how fun it is to be driving car without any training or driving license.
