What languages do you know currently? This will probably be an unpopular opinion but unless you know more than you can count on two hands, it&#x27;s unlikely that Rust or Go will be give you the best ROI if your focus is career enhancement. The largest career ROI is probably in getting to advanced-intermediate level in a couple of the following (in absolutely no order, I intentionally put ones I don&#x27;t know first):<p>- Python<p>- Ruby<p>- JavaScript<p>- PHP (especially for WordPress if your focus is web)<p>- C#&#x2F;F# and the .NET ecosystem generally (especially for corporate)<p>- Java (especially for corporate)<p>- VB.Net if you want a government job<p>- C&#x2F;C++<p>- Enough SQL to do whatever you want with the above
