What has not change is the strategy of throwing a gargantious amount of computations at the problem. If anything we throw more computations at more problems now than in 2016 (and in 1997 for that matter). The underlying technology is pretty much the same, just more parameters, more calculations, etc. Yes every individual calculations takes less power now then in 2016, but we make up for that by making millions of millions of more calculations, even for simpler tasks.
