    Starship is not yet reusable but they have the MVP and a fantastic position to iterate forward.

    -- they have an orbital launcher with the largest diameter cargo bay

    -- larger sats have bigger antennas and bigger PV area and more bus power. this scales as diam^2

    -- 26 x Starlink v3 ~40-65 tons to LEO

    -- every launch generates revenue, locks out the orbit for competitors.

    -- they can launch more volume, more mass and cheaper than anyone else by a large margin

    -- the design is validated - things will work

    -- there is technical debt, issues but the rocket did the job

    Caveats

    -- timelines for full reusability are optimistic etc

    -- there will be other issues in scaling to launching gigawats into orbit

    -- cooling will have to be

    -- Musk might go Full Villan mode before the thing works

    [meta] I really didn't like that other negative comment getting voted to the top. Looks like it's made by someone who never worked in a bigco. For every bigco I worked, at any time there were hundreds if not thousands of open issues. You could list them and try arguing the company is about to fail and you'd scare people who don't know better.

    It's the judgement of the severity of the issue that matters not #no_of_issues. And if there were 0 issues would our job exist?

    [edit] getting the formatting right is very hard, maybe we could get a preview / TinyMCE ?

      The biggest issue is payload. Right now they’re launching with very light payloads, way less than the Saturn V or even the Falcon. Definitely short of their goals. They’ve never demonstrated a real payload weight. Until this happens their progress is illusory and a skeptic would claim their engines can’t take a real launch payload weight.

        The Starlink V3 sats launched today are much bigger and heavier than the Starlink satellites they've been launching on Falcon. Even if they fit within the Falcon fairing, they'd be too heavy to launch on F9.
