Why there is pretty much no real innovation in tech industry?
Beacause there is no real Research & Development being done - tech industry is so much less than Bell Labs and so much more like Microsoft, Google and Apple. Crapload of money doesn't generate innovative breakthroughs if talented people are micromanaged and squeezed into Jira boards and deadlines, also scared to be randomly hit by another "optimization" layoffs
This is why the best the industry has to offer is the new iPhone that doesn't differ from the previous, synthetic parrot that repeats scraps of texts without any sensible context for enormous amount of energy (LLMs), and tech jobs that sucks the soul from enthusiastic geeks to exhaustion and overburn
