1. Except, the millionth LISP interpreter is almost definitely a hobby project, so their claim that people are screwing around at work is bogus.
2. What drives people to work on problems (in industry) isn't "what the nerds find cool", it's money. That's a capitalism problem, not a "this industry isn't controlled enough by me" problem. The most lucrative jobs are in enterprise SaaS and ads companies, do you think engineers flock there because that sounds fun?
3. The software industry isn't uniform. Medical devices ARE regulated under the medical industry, commercial airplanes ARE regulated under the aviation industry.
Has there been recent disasters in those industries due to software? Yes, and regulation gets updated. Regulation gets written with blood.
You might argue that software feels like they're the most prominent, but I argue it's because:
1. Software is relatively new
2. We are software engineers, so we take notice of software more.
Mechanical and civil engineers are not immune to human-injuring mistakes. Think of the last car recall due to mechanical failure (heck, there's one this year due to brake manufacturing issues: https://www.caranddriver.com/news/a44475030/honda-acura-brak...). Or the O-ring failure in the space shuttle Challenger that caused it to explode mid-launch.
