Tbf there has been a shift from manufacturing industry to financial industry.
And that financial industry bled into the other industries, and started stealing the credit.
Musk is a good example. The perfect one, really. True engineers and scientists could be the figureheads of those companies, but when you think Space X, you think of that wart of a human being.
Edison was a shithead with his company and his money, but he was still the genuine article when it came to engineering. More than can be said for Musk.
