It looks to me like there will be a replacement as the development progress has slowed to a crawl. Not to mention Diffie-Hellman elliptic Curve25519 is considered not safe.

Should I continue?

This is exactly backwards. Schneier was referring to the constants of the NIST curves. Curve25519 is not a NIST curve, which is precisely why it's been very popular among cryptographers in recent years.

From what I understand it has to do with the selection of common constants but I'm not going to research it again.

Popularity

Curve25519 was first released by Daniel J. Bernstein in 2005,[7] but interest increased considerably after 2013 when it was discovered that the NSA had implemented a backdoor into Dual EC DRBG. While not directly related,[8] suspicious aspects of the NIST's P curve constants[9] led to concerns[10] that the NSA had chosen values that gave them an advantage in factoring[11] public keys.[12]

Since then, Curve25519 has become the de facto alternative to P-256, and is used in a wide variety of applications.[13] In 2014 OpenSSH[14] defaults to Curve25519-based ECDH.
