Elon Musk warned of Cybertruck headaches, consumers' debt woes, and a 'stormy' economic backdrop on Tesla's earnings call. Here are his 14 best quotes.

• Elon Musk tackled a wide range of topics during Tesla's third-quarter earnings call on Wednesday.

• The EV pioneer discussed Optimus, Cybertruck, cutting costs, working from home, and exercise.

• Musk also warned about pressures on household finances, banks, and commercial real estate.

Elon Musk touched on everything from "The Terminator" and "Game of Thrones" to "The Wizard of Oz" and Marie Antoinette during Tesla's third-quarter earnings call on Wednesday.

The world's richest man and CEO of the electric-vehicle maker underscored the difficulties of scaling Cybertruck production, touted Tesla's Optimus humanoid robot over Boston Dynamics' mechanical dogs, and trumpeted his cost-cutting efforts, according to a transcript provided by AlphaSense/Sentieo.

Musk also raised concerns about the uncertain macroeconomic backdrop, flagged pressures in the banking and commercial real estate sectors, slammed work-from-home evangelists as delusional, and joked that he prefers gaming to working out.

Here are Musk's 14 best quotes, lightly edited for length and clarity:

1. "We dug our own grave with Cybertruck. Nobody digs a grave better than themselves."

2. "I don't think anyone is going to do it better than Tesla, not by a long shot. Boston Dynamics is impressive, but their robot lacks a brain. They're like 'The Wizard of Oz' or whatever."

3. "We need to make sure that it's a good place for humans in that future, we do not create some variance of 'The Terminator' outcome." (Musk was discussing the risks attached to developing AI, and underscoring the need for a physical kill switch on robots.)

4. "Optimus, a year ago, could barely walk and now it can do yoga. So, a few years from now, it can probably do ballet."
