I doubt it would be better.
I’ve said for many years now that my job is primary knowing what’s possible even if I don’t necessarily know exactly how to do it (today).
By reading HN nearly daily I keep my finger on the pulse of tech, or at least the parts of tech that most directly affect me. Countless times I’ve been able to say “oh, I saw a library/saas/etc that does what we need” in a meeting and it’s directly led to starting my own company. When a company came to me asking for software I was able to say “yes that’s possible and I’m capable of delivering it”, in great part due to following advancements/products/etc in tech even when I hadn’t used some of those specific tools before.
Personally I shine the brightest when I can pair my knowledge of technology with someone who is a subject matter expert (outside of tech) to create something they didn’t think was possible. I’ve often thought my dream job would be to go into non-tech companies, learn enough about their industry, examine their processes, and then suggest and/or implement solutions (revolving around the use of technology) to improve them.
I don’t know of any place, other than HN, that has high quality posts and discussions about technology and new things coming out.
