Earlier quoted context omitted.
It's not even clear that the premise is true. There's lots of 'research' done in the big tech companies. The biggest reason why companies don't seek to emulate "Dupont, Bell Labs, IBM, AT&T, Xerox, Kodak, GE", is probably that it reads like a list of textbox examples of "companies that failed to execute on their research findings", so clearly there was something wrong with this approach.
The bigger problem today is that there is simply nothing more left to research. Everything that is being worked on are at most optimizations, which allways have a dollar spent vs dollar returned amount on them.
If it feels like there’s nothing for us engineers to research, that’s probably a sign we need more basic research from the scientists!
