The main thing that makes me suspect we might have AGI before 2100 are neuroprostheses: in addition to bionic eyes for humans, we've got working implants that replicate parts of hippocampal and cerebellar function for rats.
The hippocampal implant has been extended to monkeys.

I want one!
Kim Suozzi was a neuroscience student with brain cancer who wanted to be cryonically preserved but lacked the funds. She appealed to reddit and a foundation was set up, called the Society for Venturism. Enough money was raised, and when she died on the January 17th, she was preserved by Alcor.
I wasn't sure if I should post about this, but I was glad to see that enough money was raised and it was discussed on LessWrong here, here, and here.

Edit: It looks like Alcor actually worked with her to lower the costs, and waived some of the fees.
Edit 2: The Society for Venturism has been around for a while, and wasn't set up just for her.
