I&#x27;ll extrapolate from my personal coding history. Late 70s to mid 80s was Basic, Z80 &amp; Forth on Pets, ZX81 &amp; Lynx. Professional career started in 85, and that was Fortran &amp; C up to 1992 when I started coding in C++. Added Java in 97, Python in 2000 and C# in 2002. I&#x27;ve dabbled in R &amp; Cobol at various times. I&#x27;m coding in C++ and C# today. I expect I&#x27;ll still be coding in C++, C#, Java &amp; Python in 10 years time. Maybe Rust will be in the mix too.
