I think the AI question was always the limiting factor. Until this year General AI was more or less theory but more and more it seems like the software problem may be well on its way to being solved. Hardware is getting there as well as data centers are being built to specifically run these AI algorithms. GPUs are being tailor made to run these as well. If anything, we are officially about to come out of the knee of the curve and will see progress this decade no one would have believed even last year.
