I just got off the waitlist. Quick impression: it's not as good as ChatGPT. I gave it the false belief test (Alice and Bob are playing, Bob leaves, Alice hides his toy, Bob comes back, where does he look for his toy?), which it both passed and recognized as the false belief test. I then asked it to write a React program that ChatGPT has no problem with, and it hallucinated some incorrect code before eventually telling me it "can't do that." It's underwhelming so far.
For the record, here's the prompt and the result [0] from ChatGPT:
> Write a react program that I can paste into a codesandbox. It should display a counter that increases by one every second. Below the counter is a button, and when I press it, it decreases the counter by two. If pressing the button would result in the counter decreasing below zero, the button should be disabled.
To be fair, the Google FAQ states that Bard doesn't know how to code yet. I can confirm that's definitely true!
