In the beginning, Kellogg and Rice invented the electrodynamic loudspeaker.
Shortly after that, people starting worrying about foam surrounds rotting out.
OK more seriously, is this a thing with new speakers any more? I recall a nice fellow Neal Baitcher from Nu-Way speaker component company working on that and saying it would be a thing of the past. I still hear about foam rotting out: is that only ancient speakers? Or do newer foam surrounds still rot eventually.

Time will tell.
There is a vast improvement in foam technology.
On the flip side, as with anything.
It is highly likely to be low cost and higher cost options.
Coming from other industry using foam.
It really depends, because low cost options can degrade rather quickly.
Im trying to remember a recent datasheet I reviewed recently.
Which boosted a non degrading foam. Using a additional coating

Still a thing. But you can grt higher quality foam today, does not mean all are better though.
And most apply a layer of coating to help with uv protectionand longevity. Although it slightly affects the foams behavior.

I don't like foam surrounds for the reason that they DO deteriorate earlier than rubber > as mentioned.
However, when new, a coat of ACETIC CURE silicon can extend life significantly. DO NOT USE NEUTRAL/SOLVENT CURE SILICON.
This silicon treatment will increase Fs and hence Q to a degree.
