Great write up, will be curious to see if Astro sticks around. It seems like all the static site gens last a few years then fade away - Jekyll, Hugo, Gatsby, etc.
Me too! The closer my framework is to raw HTML, JavaScript (really TypeScript nowadays), and CSS, the less lock-in I feel. Those 3 languages are continue to get better year over year. And we are get better framework abstractions every few years too. Astro feels like it hit the sweet spot, but maybe there is more to come.
