SpaceX has permission from regulators to launch up to 12,000 platforms but has talked of an eventual 40,000, depending on how the project develops.
40k satellites?
Once I saw a graphical presentation of 3500 satellites orbiting earth and blew my mined.
But 40k?

Hopefully, they will be able to keep the satellites cool, after painting them

stealth black...
But apparently they have a fixed orientation so only the bottoms have to be
painted black. And Earth isn't a good place for infrared astronomy anyways.

New economy is coming, robots, self driving cars or farm tractors, drone delivery etc...
it needs fast internet and 5G will provide it.
New capitalist tool to shrink the world smaller and enslave us more.

Does this mean we all get free Internet service!?

I don't see these as representing any major threat to astronomy,
outside of a small issue for some radio astronomy. Amateur imagers
will be largely unaffected since we almost always stack frames, which
removes airplane and satellite tracks. You can bet that any
professional observations which could potentially be impacted (which
isn't all that many given that they usually operate at very small
FOVs) will plan around interference using published orbital elements.
Really, the satellites are more of a minor inconvenience to astronomy
than anything else... in exchange for pretty major societal benefits.
There's too much useful stuff that can be accomplished by
constellations of satellites in low Earth orbit. There's going to be a
lot of stuff up there; that's just the reality of it.

Which demonstrates that most professional astronomy isn't greatly
impacted, and that steps to mitigate impact are being developed, and
that where specific issues exist there are opportunities to address
them.
