I think it's fairly common for technologies to get really good just as they're becoming obsolete. Vacuum tubes, CRTs, optical disks, photographic film... in fact, they're often in some respects better than the early generations of the technology that replaces them.

But OLEDs just have too many advantages where it actually matters. Much lower power consumption, physically more compact (no need for backlight layers), etc.

For me, OLEDs fall into a category exemplified by Anton Gudim's "YES, BUT" comic series.

YES, OLEDs consume less power, offer truer color reproduction, and are physically more compact.

BUT, they are prone to CRT-like burn-in.

SSDs, the same thing.

YES, SSDs are much faster and immune to mechanical failure.

BUT, they tend not to last as long as HDDs due to limited write cycles, and their price per GiB is still much higher.

You might add ICE cars to that list. All kinds of cool stuff being developed around small turbocharged engines and other efficiency gains, excellent transmissions, etc.
