Perplexitys methods are bad but the concept of a natural language web browser is a completely unique thing and thats interesting to me. Its like when google enabled people to search "how to change a tire" instead of before where people searched with keywords.

Idk how you can say self driving tech is not cool. Even the worst self driving which is Tesla's is still very impressive. Telsa can drive autonomously through the street using only cameras. Is it perfect no but its still very good and its only a joke because of how good the competition is. That gives me a lot of hope for self driving cars.

As for that Chinese robot dog yeah I see the video that got put out, I dont think it blows away Boston dynamics version in anything but manufacturing costs. All the falling and all terrain movement the Chinese dog can do has been done by Boston dynamics for almost 5 years at this point.
