The Sun is going to fail in somewhere between many hundreds of millions and a few billion years. This will either turn the surface of the earth into slag, freeze it, or both. Either way, all life on the planet is doomed. This fact is not a reason to fail to switch from hydrocarbon-burning electricity generators to photovoltaic, fission, wind, hydroelectric, and geothermal electricity generators. Extinction events that will happen in the extremely distant future shouldn't prevent us from doing the things that are smart to do in the medium- and long-term.

But, -to bring things to the present day- companies that are solidly on track to hit their promised growth targets don't come out and publicly say "We're working on WMDs. [0] We are incapable of safely working on these WMDs. We refuse to stop working on these WMDs. However, if you lawmakers make special laws and regulations just for us and include us in the process, we'll be quite happy to submit the stop work order to our employees!". That's a statement you only make if there's no way in hell you're going to keep your promises and you're willing to risk jail time and annihilation of your companies for a shot at being able to con Congress into giving you an ironclad excuse to fail to keep your promises.

Given enough time and focused effort, we will end up with widely-available automated librarians that are very good. We're not there yet, and -based on current events- are absolutely not going to get there in the near future.

[0] Anything with a 10% chance of destroying all humanity is a WMD.
