I think that's just a mindset that made sense when tech was new. As this becomes just a part of life, I think you'll see a bifurcation between established tech and "new stuff", where the established stuff is treated more like a utility.
In some ways we have that now, it's just not flashy. There's countless websites (think Craigslist) that pull in predictable and reasonable income for the folks that run it.
I'd prefer a world full of those versus a bunch of megacorps using tactics of the KGB to try to increase their revenue by X% every year.
That's a pithy, vivid snarkonym I suppose; 10/10. The reality is that things don't exist in a vacuum: competitors exist and one of the best defenses against competitors is growth. Growth provides affordances, such as ample capital, market profile and regulatory leverage to counter competitors. Certainly one can conceive of alternative ways of surviving competitors, but it never hurts to be a thriving concern. That's hard work for all involved though, so better to simply spiral the rest of the way down and condemn competition as well: perhaps "The Market is societal metastasis".
Or something. You'll get there anyhow, so best to start working on the next clever derogation now.
I agree with your response, but I also think it's an unsustainable model, which is why it's a "mind cancer". Growth makes things easier but nothing grows indefinitely, and that mind-set has done a lot to create climate change problems.
That's the buyer seeking growth, even if only to shut the bought down, yielding relative growth. Big fish eat little fish. That's the universe talking, as opposed to whatever ideology you prefer to blame.
The "solution" -- should you perceive a problem with all this -- is destabilizing the large such that the small find more opportunities. Hating on growth isn't compatible with this, however: you must be capable of tolerating the small enjoying growth.
When it comes to the personal and intangibles, then grow all you want; read the books, develop the skills, and so on. But when it comes to consumption of resources and economic growth then cancer is the right word as unbounded growth fundamentally results in unbounded growth of waste products and overconsumption of inputs.
There is no system or ecology that can support infinite growth; as long as we're stuck in the "coasting is dying" mentality we'll see productive entities develop dysfunctions as they outgrow their ecosystems or kill themselves trying to expand. If coasting leads to gradual decline then over expansion leads to catastrophic failure.
