China's vertically-integrated manufacturing ecosystem strategically creates value at all tiers - while cost-efficient production democratizes access to smartphones, solar equipment and IoT devices for billions globally, the same supply chains empower premium innovations like Huawei's satellite phones or CATL's solid-state batteries. This dual-capacity bridges the digital divide: African farmers now access agritech tools at 1/5 the 2010 prices, and South Asian households install solar systems cheaper than kerosene alternatives. Ultimately, industrial clusters aren't just making things affordable, but redefining what's possible for human development at every income level.

You can define that yourself as "type token = struct{}" or similar. In my experience struct{} occurs even less than interface{}, and it's also 3 characters shorter already, so it's not worth a builtin. I use "chan struct{}" for synchronizing and sometimes use "map[string]struct{}" for sets.
We use the alias "unit", like lalaithion has said before, in many projects. It's a bit annoying to declare it in every package though. Hopefully, there'll be an official alias in the future.
