Not much more to say really, things are slowing down, improvements to products are minimal.
Actual, genuine newfangled technology what is there? Everything is an iteration upon an iteration.
We still use the microwave, we still use the freezer, the cooktop, the oven, we mostly use the combustion engine, we still mostly use steam for power plants, computers have gotten faster and we have LCD's now but nothing huge has hapenned, we don't have anti-gravity, we don't have teleportation, we can't change one thing in to another (easily), medically we still aren't growing replacement bodies.
Yes things have gotten better but I haven't seen a huge revoloutionary change to be honest in my lifetime, maybe the mobile phone I guess.
I'm not sure I understand why people complain about things like this. Yes, we still use the microwave. Know why? Because it works well at cooking certain foods. Yes, we still use the knife, an invention that's thousands of years old. We still use the knife because it's good at cutting things and there's no real reason to go back to the drawing board on that particular task. The fact that we are still using inventions that are old doesn't mean progress is slowing down, it means we're smart enough to know when to move on to something else.
In my life time I have seen technical advancements such as:
-Cloning
-Stem cell research (which WILL be a revolution I'm sure)
-The internet
-Cell phone
-Pictures from the surface of another planet
-Pictures of another planet from another solar system
Yeah, some of those might seem incremental, but everything always is. Technology doesn't ever undergo revolution, it undergoes evolution, as Issac Newton said "If I have seen further it is only by standing on the shoulders of giants."
