Not quite, the true invariant quantity is the magnitude of the spacetime 4 vector, which depends on rest mass.

I'm not disagreeing with that, but high speed rail from Boston to Miami would be extremely practical. Efficient, fast, convient travel along that corridor reducing dependence on cars for city to city travel. And the area has both the demand and density to support such projects.

And while its impractical now, if it was built to cheapen regional travel in the region it could grow to high use spurning economic development.

I'd love to take a train at a reasonable pace from near to DC to my family in Pittsburgh, or to visit New York.

I might even enjoy a cross country trek to the rockies for skiing on a train, but it's never going to be an option.

Bedrooms do have to have windows or a door to the outside to be legally a bedroom.

What's so mind boggling stupid to me is that full evs are mechanically so much simpler.

Their reliability should be fantastic.

But no oems cheap out on things like contactors in the battery.

Batteries should also be treated as consumable. Easily replaceable, maybe even in parts.

Electric motors seem like they should last forever too.

But nope, instead we get skimped cars with too big batteries, and seemingly no money spent anywhere else.

Manufacturers need to remember that planned obselesence only works when you know what your doing, and right now they early don't.

But it's text, an entire persons message history can be stored very cheaply.

A million words is only 2MB.

Most people are expexted to text less than 10 millions words in a lifetime.

An entire persons lifetime message history is only 20MB, that's trivial to store.

If they want to charge to save media, thats fine, but text backups should be free

If you're barely scraping by, having less money can significantly affect quality of life, or at least percieved quality of life.

I'm not on beehaw, but I ran into similar problem when I joined lemmy.

My solution was to filter communities and users where I felt I was getting apammed with content at a frequency I didn't enjoy.

You might get some milage out if that approach.

I wish they had done another test with a decent lock.

Honestly, it's so easy to block accounts, so if there's only one bot in you community you should just keep it.

If they don't like it they can block it.

4g of CO2 per email? I find that hard to believe. Probably overestimating emissions like some media did with Netflix.

Recent controversy over an absurdly high failure rate.

Might be fixed now, but i wouldn't gamble.

Give it a decade and economies of scale, and maybe it will get it down to twice as expensive.
