“Tech”? What do you mean by “tech?” Do you expect Apple to remove the camera, storage, and networking capabilities of all their devices? That’s the “tech” that enables this.
Enabling people to talk to each other without all their communication being wiretapped and archived forever is not one of those, I would say.
Uber and AirBnB are just using very-widely-available technology—that some taxi services and hotels are also using!—and claiming that they're completely different when the main difference is that they're just ignoring the laws and regulations around their industries.
Cryptocurrencies are using a tech innovation as a front for what's 99.9999% a financial "innovation"...which is really just a Ponzi scheme and/or related scams in sheep's clothing.
LLMs are genuinely a tech innovation, but the primary problem they bring to the fore is really a conversation we've needed to have for a while about copying in the digital age. The signs have been there for some time that such a shift was coming; the only question was exactly when.
In none of these cases is technology actually doing anything "messed up". Companies that denote themselves as being "in the tech industry" do bad things all the time, but blaming the technology for the corporate (and otherwise human) malfeasance is very unhelpful. In particular, trying to limit technological progress, or ban widely useful technological innovations because a small minority of people use them for ill, is horrifically counterproductive.
Enforce the laws we have better, be more willing to turn the screws on people even if they have lots of money, and where necessary put new regulations on human and corporate behavior in place (eg, requiring informed consent to have works you created included in the training set of an LLM or similar model).
