"nothing has really changed in the past two decades"
If we discuss consumer products, then I would be willing to agree up to a point. Except, for example, we are finally getting electric cars that drive by themselves. This not just an improvement in computing. Geneticists just got crispr which means there will be an explosion in gene altered organisms.
I'm not sure what kind of big changes you are crawing - these do not reflect the state of the art in sciences but rather what products are manufactured and marketed for consumers. Two decades are actually a really short time for any sort of significant development in any field - although improvements tend to come in bursts.
