I share the sentiment actually (to a degree).
It was one of my hidden motives to become an indie, and to effectively do it 'all on my own': know every angle.
There's a lot of satisfaction with doing more parts, being 100% responsible for a brick is more satisfying than 1% of a NASA shuttle.
That being said, that train of thought originated in the fear of not being able to do 'shit' after an apocalypse. My fear of not being able to properly build some of the commodities of today (Microwave!) led me to try to have a more hands-on experience. The compartmentalization of our society had led to great progress (otherwise un-achievable), but it also makes it that much more frail. However unlikely, what if all engineers and engineering books disappeared? How would the rest of us fend for ourselves?
I generally don't think too much about that, until somebody else mentions it obviously ;)
Yeah, I very much share this sentiment. Even though specialization is great for the economy, I cant stand not-knowing. I may not be the best programmer, the best mathematician, the best physicist, or the best biologist, but my employability in knowing a whole lot about all of these subjects is just fine, and I get to do actually interesting work. Aspiring to be a generalist has worked out for me. Lying here in my self-constructed bed, Id like to think id do relatively well if society did collapse.
