I saw the news that Tesla can be using the bot next year. This is faster than I expected and is very exciting. While I expect it to be not as efficient early on, if they can continue this pace, I can see your target of 2027 to be very feasible. If they can get more advancements in the AI, then it could even come earlier.
Things are ramping up in the technology world. Meta's release of Llama3.1 caught most off guard. A ton of stuff happening.
