Architects can also focus on design, which reduces the need for a rigorous engineering training. An architect doesn't have to be a construction engineer.
For example, Tadao Ando started as a truck driver and became one of the world's most celebrated architects with no formal training:

The software world is missing a job title that would approximate the role of a design-oriented architect. There are plenty of software architects, but this is usually a misleading title because they design infrastructure rather than public-facing spaces. The software architect is more like a "software municipal engineer".
