I'd even say there has been very little fundamentally new stuff for the last 100 years.
Depends on what area of technology, and what you consider "new" as opposed to a "technical refinement" or "manufacturing advance". Does the transistor count, or is that just an incremental improvement on vacuum tubes? The physics required to build, say, an iPhone were mostly understood by the 1920s, and I don't think there was any theoretical work suggesting that it was impossible. On the other hand, the concept of ubiquitous handheld multi-functional computing and communication devices connected by a global network containing nearly all human knowledge required levels of technology that couldn't even be guessed at.
If you consider the life sciences instead, our background knowledge is as far beyond 1920s biology as the iPhone is beyond the telegraph, and revolutionary discoveries and technical advances are still being made.
