Which programming language would you choose if you had to rely on one for the next 20 years, and why?

Assume you must depend on a single programming language for 20 years. Which language best meets your needs in terms of safety, performance, readability, and ecosystem? Please explain your decision.

hey all, i think rust might do the trick thanks to its safety and speed, even if its syntax is a bit off sometimes. have any of you tried it for big projcts? what do u reckon will be the next big leap in its ecosystem?
