Good question. I suppose the Terra Cotta liners are, like, 13th century technology. About time for an upgrade.

Hmm. Are you implying a negative towards masonry liners? Masonry clay liners are tried and true with a long proven history. Check out this article.

Absolutely not. I love old stuff. Come on over for a visit, and have a beer with me in my 18th century house, outhouse included. My two stone chimneys didn't have anything lining them when I moved in.
In direct response to the question asked: In a new house with a cinder block chimney, wouldn't an insulated stainless liner be better than clay tiles? I'd say, probably, in my opinion, yes.

Honestly that article is full of misinformation. Clay liners do not typically last 50 years if used on a wood appliance for heating or for oil or gas appliances. They are still the best liner for coal but otherwise a good stainless liner with insulation will outlast and outperform clay.
Because liners are required by code. Many still have clay liners which are still perfectly code compliant. But they are not as good.
"Insulated" being one of the key words here. Just a better experience with an insulated liner IMO.
I think the clay liners are more of a 20th century "upgrade" to chimney construction.
In my "neck of the woods", there are many unlined chimneys being used for gas or oil furnace venting, and, even wood stoves. Despite Oregon's very strict law on removing old pre-epa stoves, they are still being used by skirting the law ( & less than ethical real estate people, that ignore the law stating they need to be removed at sale, with proof of scrapping!). The mentality often is -- "the chimney has been fine for 100 yrs., & will continue to do so." Chimney's often are just cleaned by the homeowner, a friend, or a local "handyman", who may not have any kind of license, much less be a certified sweep.
My only point is............that what should be & what actually is/exists are often two separate things. Simply pay attention to what bholler has to say & the other good advice given here -- SAFETY is of primary importance, not what has always (seemingly) worked.
