A lot of the 2010's tech was fueled by venture capitalists looking for the next big thing. They saw things that were extremely popular, like Facebook, Reddit, YouTube, etc, and figured "well we've got a ton of users, surely we can find a way to make money off of this."

Some investors are starting to realize they aren't actually making much money or costs are blowing up without revenue following. People are starting to back out of this bubble without clear goals towards profitability.

That's the same argument for (some) Imperial measurements, but people converted to metric anyways.

I think it's because there are important, naturally occuring units of time that simply don't divide well - that is, the day and the year. Having it standardized to metric would still leave us with 1:365.24 conversion. Using metric time would require us to stop being metric beyond the day, or just have a cumbersome conversion number to talk about years.

On the other hand, things like weight, length, and temperature are completely arbitrary and there's no natural standard unit, so changing those to another completely arbitrary unit is easy.
