I read in bed on a Kindle and have found that lower brightness is helpful in calming before bed, regardless of whether I have the warmth up or down. The "dark mode" feature that inverts the screen I have actually have pretty poor experience with - I find it harder to read the words which leads to more straining which is counter productive. The only "benefit" I see of this feature is to decrease the overall light in the room which might be helpful for others sharing the bed etc.
Huberman concluded this too - dimming lights at night is better than blue-blocking [1].
I'd like to see a study using Flux on computers for those working late at night and then trying to sleep. Assuming the stimulation of a late work session would diminish sleep quality regardless of light color, but which is "better" at allowing the participant to fall asleep quicker/ higher levels of deep/rem would be helpful. If you're doing anything to do with design Flux is a big no no.
I think it goes to my earlier point that they're so massive now that they need to ship huge bets to move the needle even a little bit. Gmail and Search both are valid, but to an earlier point are now decades old. Both of these businesses have used inorganic growth for their needle movers - the acquisitions that changed the game for them: Meta was Whatsapp and Instagram; Google was Youtube and DoubleClick.
Meta is becoming more like Google in it's wide ranging products in disparate markets and ultimately shutting them down one by one. Unlike Google they seem to be more focused and therefore it's good to see the shuttering of Workplace given it's not a strong contender in it's market.
For most large businesses in order to move the needle they need to be making really large bets in a few really large markets to keep growth. A Slack alternative would never move the needle for them, given the most successful (Slack) sold at the top of the market for a "large" amount of money, which was $28B (only ~2% of Meta's market cap today).
Shutting down Drizly means shutting down it as an independent app - the same merchants are available on Uber Eats for the most part so you should be able to get alcohol delivered via the normal app.
