This is the cost of complacency. They were ahead for so long then the likes of Roborock just left them in the dirt. I remember the first time I tried one of the Roborock devices, and until then I have been a long time Roomba user (like, 20 years). I just couldn’t believe how much better it was. And iRobot just stubbornly refused to iterate on their fundamental products.
It is complacency or is China just accelerating? It's not surprising that China wins in these things. Just go to Shenzhen. Hardware designers, parts, machines that make the parts, factories, etc. are all within driving distance. You can't compete unless you also have offices there, hire Chinese workers, compete in China. American companies need to start designing in China, not just made in China. Ford themselves said…
Cisco is now essentially a publicly traded PE firm that buys up other companies to milk dry. Most internal development is outsourced by suits far removed from any qualifications on quality.
We all know the foibles of Boeing, where accountants made the final calls on everything.
The only innovations the traditional American car companies seem to be able to focus on is how to make cars bigger to increase margins. It's ludicrous that it took a new company (Tesla) to make electric cars available.
I could go on. This is not to say that other countries (including China) don't have their own issues with their business climate, but the United States has an environment where some of the smartest and best paid people in the country are working their asses off to find out better ways to show ads (Google/Facebook).
