Fred Brooks wrote about that idea in 1975. It seems that the management side still has not learned the lesson.
so everyone else just hires older people, but it isn't sexy and marketable to the impressionable technology crowd.
I can't imagine you'll find many older, experienced devs willing to put up with the "we need to ship so you've got to put in 80 hours this week.

- Was the toolsmith idea about some people in the team building tools, that others in the team use for the project? - and if so, what was the benefit cited - specialization?
- What was the second system effect about? I know I can google, but interested to read your take on it first.
Yep. The benefit is efficiency. However, modern SCRUM advocates simply advocate grinding away at stories.
"What was the second system effect about?"
The glittering new rewrite of an existing system is usually overengineered and worse. Seen it several times.
And at least in one case, it was: in a C database middleware product that I worked on, as the team leader. It did work earlier but had big issues of bugs, slowness, memory leaks, and maintainability. There were many reasons for that, including complete freshers put to work in it (a mistake). After me and a small new team took over, we improved it a lot and fixed all those issues. It went on to become a much more successful product, deployed somewhat widely within the company, for client projects ...
