Nothing would make it “help get a little closer to making it a reality” if it’s not physically possible, and there’s a very strong argument that that’s the case. If nothing else, the maximum specific tensile strength allowed by covalent bonding - which is fundamental physics that we can’t change - combined with the reality of defects in a 36,000 km cable - is far below what’s needed to build a space elevator in Earth gravity. It might be possible to build a space elevator on the Moon or even (in the far future) on Mars, because their gravity is such that real materials could potentially do the job. But doing that involves bootstrapping an entire offworld industry, which is far beyond anything even the most advanced nations are capable of currently, let alone a technologically stunted oil state.

If you go to a Ford dealer, the salesman isn't going to recommend a Porsche. If you go to Taco Bell, they're not going to recommend Wendy's.

Lots of folks have experience installing gas furnaces. That's what they know. They don't know heat pumps. They could learn, but learning is hard. If they can keep selling gas furnaces, that's easier.

My home is made with cement blocks - just like most houses in the UK. It's a massive thermal mass.

I installed heat recovery ventilation which also helps hold heat in while maintaining a constant supply of fresh air.

Which means that temperature swings outside don't really affect me.

I've been using it for five years now. I'm aware how much electricity costs. But for me, it's discounted by 33% due to solar PV. And my heat pump is 150-300% efficient.

When it makes sense to replace the roof on my house I can double my solar capacity and I'll increase my electricity storage capacity.

So long term it will cost me way less. And, as I noted, the benefits go beyond cost. It's quieter, it's not spewing fumes outside my house, my home has less fire risk, etc.

I installed a heat pump back in 2021. It's fantastic in an Irish or British climate. Home's much warmer and much quieter. Don't need to have CO monitors in my house, don't need to remember to schedule oil deliveries, and so many more things. I can stand outside my back door and not get assaulted by fumes.

All the energy I use at this point is electric - heating, cooking, transportation, all of it. And I offset 33% of the electricity I use via solar PV. When I need to replace my roof, I'll put panels on my house and double my solar production.

This matches how I use it. I’ll add a few other points:

4. Writing the first core version of a service or UI. I’ll typically use close to 100% of those generated lines, and then continue building with LLM assistance where it makes sense. It makes a big difference to development velocity.
5. Finding bugs. If some bug isn’t obvious to me, provide the code to an LLM and describe the problem. Its success rate is high.
6. Working with tech I’m not particularly familiar with (an extension of your #3, i.e. learning)
7. Writing documentation.
8. Reverse engineering existing code, i.e. describe some code to me so I don’t have to dig through it in detail.
9. Writing unit tests.
