AI Hardware Development
Hardware teams are building systems more complex than ever, but coordination capacity is not keeping up. AI will not fix this as a bolt-on feature. The next decade belongs to teams that build AI directly into how engineering systems work.

Hardware development's biggest problem is not engineering. It’s communication.
As teams grow, the real bottleneck is not technical skill. It is how engineers stay aligned across disciplines, tools, and programs. The fastest teams treat communication as a system and iterate it as fast as the product.
