Would you say this promise has been fulfilled?
Other solutions rely on geo-fenced known areas, LIDAR sensors (which will never understand the whole picture e.g. coloured traffic lights), and non-generalised AI. What Tesla is shooting for is much more ambitious, and much more likely to succeed in my opinion.
Why be pedantic about forward-looking announcements, rather than celebrating the incredible things Tesla AI has acheived so far (and continues to acheive)? The cars can now navigate competently through city streets. That was sci-fi just a few years ago.
Also, it's not being pedantic when you point out that someone is over 5 years behind what they promised...
