imo computers and the internet are such potent dopamine feeds that our brains get used to the constant stimulation, making real life boring and causing us to be anxious when we’re not getting our fix. And this is heightened when we use the computer as an alternate world to escape to, and feel more comfortable in, when we don’t feel safe or welcomed in reality.
It is valid and maybe easier to see with a comma.
“I am marrying, today.”
“Today, I will be marrying.”
It is valid in the context of “i will be engaging in marriage, today (“today, i am entering into a covenant of marriage”)” but it wouldn’t be something that would be heard very often. it’s a more archaic usage.
