The only time I replaced plugs was on my '76 Yamaha RD400 two-smoker. Sometimes I just got lazy.
All my other rides never saw plug changes. Yes, perhaps cleaning/re-gapping, but that was it.
With many larger bore modern lumps with a pair of plugs per cylinder, I reckon the probability of getting a spark is better. I definitely never changed plugs on those configurations.

Had 2 sets of spark plugs ordered a few days ago, and took the old ones out today. They look like Max's plugs. Given that the plug type for the CB1100 is a special one, and there aren't many CB1100 around, I figured it's good to have spares for such plugs which no other engines need. But when I look at my old spark plugs ... I guess I am now equipped for at least 150,000 miles on the CB1100.

In theory, and with favorable riding treatment of the CB1100, yes - the OEM plugs are very long lasting.
This can be empirically observed for many Honda internal combustion engine products.

Because of good situations like this, devices like these can stay out of landfills, longer.
With practically every member of a household wanting a cage these days, and some households sheltering more than one family, the pressure is on the landfill more than ever.

Believe it or not...there are numerous different plugs available for our bikes other than the Honda part #.
I have a set of NGK 'performance' plugs sitting on my shelf...and once the weather warms I will set the rolling road in motion to see whats what...

The earth is mighty wide and deep...
As long as said fills don't leach toxic into water supplies or offgas into the air... no biggie.
I'd MUCH rather a landfill than end up in the sea or burned into our air.
....and a sparkplug is metal and porcelain.. so, why take this into politics?

Should have read this thread before buying sparkplugs! I think I'll hold off installing them. 14K on one bike, 11K or so on the other.

My 2018 Triumph Tiger 1200 had a "spark plug inspection" in the service schedule every 10,000 miles. This involved taking off a load of panels and the fuel tank, removing and inspecting them. There was no other reason to have any of those parts stripped, no other checks or air filters etc. All that work for a spark plug inspection.
I told the dealer not to carry out this work, I wasn't going to pay ther labour and it was plain stupid. It was a crazy service item specified by Triumph to generate billable service hours for the dealers. Lots of owners complained and did the same.
Miraculously when the current generation Tiger1200 was launched the service interval doubled and no mid life inspection was required! 
But it's not all sweetness and light, my 1952 MG TD EATS spark plugs
