I'll extrapolate from my personal coding history. Late 70s to mid 80s was Basic, Z80 & Forth on Pets, ZX81 & Lynx. Professional career started in 85, and that was Fortran & C up to 1992 when I started coding in C++. Added Java in 97, Python in 2000 and C# in 2002. I've dabbled in R & Cobol at various times. I'm coding in C++ and C# today. I expect I'll still be coding in C++, C#, Java & Python in 10 years time. Maybe Rust will be in the mix too.
