The Boring Company seems to be trying with different thoughts and ideas for making these tunnels a reality and they have been quite open to the public with these ideas. It feels to me that the author is taking advantage of this transparency and using it as a weapon for his own agenda.
The entire "demo" was a proof-of-concept that they can use as a model in order to see if it works or not, there is nothing wrong with it. It's not like they will be deploying the current idea to the general public of LA starting tomorrow.

Well, they are still developing the technology, aren't they?

The idea he presented in the press conference is that the tunnels would complement the current highways and public transportation system, it wouldn't be a full replacement for those.
Adding new lanes is incredibly difficult because it would require road work, blocking the entire road to traffic, and also because you are physically limited to the number of lanes that you can possibly add to the road.
The idea of tunnels is supposed to work around these limitations.
