Why can't people write things anymore.
Why do they have to make videos? Is it because they can't write, or is it because of ad revenue?

Please, in your own words, define the word "interview."
Wouldn't it's output just gradually decrease as it burned through its material?
Since its birth 4.5 billion years ago, the Sun's luminosity has very gently increased by about 30%.3 This is an inevitable evolution which comes about because, as the billions of years roll by, the Sun is burning up the hydrogen in its core. The helium "ashes" left behind are denser than hydrogen, so the hydrogen/helium mix in the Sun's core is very slowly becoming denser, thus raising the pressure. This causes the nuclear reactions to run a little hotter. The Sun brightens.
