Looks like it's a little more recent .... The 16th Century. http://www.phrases.org.uk/meanings/a-fool-and-his-money-are-soon-parted.html

Yes, PT Barnum was incorrect.

 

And now, for both the enthusiasts and skeptics out there, anyone can now experiment with a 5-qubit quantum computer, available online from IBM:

IBM established a landmark in computing Friday, announcing a quantum computer that handles 50 quantum bits, or qubits. The company is also making a 20-qubit system available through its cloud computing platform.
...
The announcement does not mean quantum computing is ready for common use. The system IBM has developed is still extremely finicky and challenging to use, as are those being built by others. In both the 50- and the 20-qubit systems, the quantum state is preserved for 90 microseconds—a record for the industry, but still an extremely short period of time.

50-qubit systems might not be so special anymore.

Are they doing any better programming them than before? My understanding building them was a challenge once mastered the next challenge will be harnessing the potential.

That's right. The real change will be finding useful applications. But that's the way pure science works. By learning all you can about the subject of interest, and leaving it to the engineers to further develop the technology and find practical uses in the real world.
