Ask HN: What technologies will we still be using in 20 years?

For example, I assume that in 20 years Python will still be popular, meaning that at least one of the existing web frameworks will still be popular. I suspect Postgres and SQLite will be in still, but MySQL will be out almost entirely. I presume Flask will fall by the wayside.

In your field, what do you think will still be in use and what will be either deprecated or just entirely out of favor by that point.
