That's really just being a Luddite, I understand the mindset but that's a very poor strategy if one cares about job security. A (good!) senior developer has a ton of value outside of the pure mastery of a language specs, not to mention that learning a language for 1 year with 15 years of prior knowledge really doesn't lead to the same level as a student who does the same.

That kind of value only matters as long as you can find an ecosystem of companies that can be convinced to pay you what you think that value is worth. Many companies can't be convinced to do so and the companies that can are overflown by candidates smarter than you that have regular contributions in top rated github repos if they haven't made super popular frameworks and libraries
