even if we don't reach AGI anytime soon there is still many new applications for current AI that we haven't explored too much yet. Robotics will be a huge one IMO.
The problem with your comment is: would this approach support these valuations? And also for robotics, is a company like OpenAI even anywhere near being able to use their tech for robotics?
OpenAI made an agreement with Figure - robotic company. Today figure is supposed to announce something so let's see how is the progress going.

Google made a lot of money with ads in Google search - eventually perplexity or searchGPT will have some ads. Maybe they can also make money with affiliate links.
Sora et al will shake movie industry and commercials.
Voice assistants and chatbots already change call centers.
It's been just ~1.5 years since gpt3.5 release and 2 years since stable diffusion - e.g. iphone 2g wasn't mainstream and they sold only 6 million devices in first year, today they sell 250 million iphones a year
