I don't like it. It seems more juvenile in the same way comic sans gets criticized for. The loss of character on the lower case g is especially unfortunate.
I really like this new look, but really hated Facebook's move away from Klavika earlier this year. This to me feels more friendly, fun, and still has personality whereas I feel Facebook's new logo is dull and lifeless.
It is because the terminal cut of the g attempts to geometrically bisect the bar of the e, whilst simultaneously trying to resemble a smile. Those are irreconcilable design objectives. The capital G is still wasting vast quantities of space. I agree, overall, this new typography has a kindergarten aesthetic. It's not for me, certainly.
However I think the colour blocking and letter shaping on the new favicon is superb.
It seems off-putting right now, but even the Airbnb logo redesign has become less offensive looking over time looking so I think people will adjust to Google's new logo and look back and see the old version as outdated.
The smaller version of the logo looks just like comic sans to me and if I'm not directly looking at the bigger version I also see comic sans. I am really not liking it.
