I used to use Google assistant to spell words I couldn’t remember the spelling of in my English classes (without looking at my phone) so the students could also hear the spelling out loud in a voice other than mine.

Me: “Hey Google, how do you spell millennium?” GA: “Millennium is spelled M-I-L-L-E-N-N-I-U-M.”

Now, I ask Gemini: “Hey Google, how do you spell millennium.” Gemini: “Millennium”.

Utterly useless.
