What's wrong with farmed algae?
IBM had a customer base in large systems and global infrastructure matched by no one.
34 years ago, the personal computer industry was t-i-n-y. Therefore, it was ripe for exploitation and expansion by *lots* of companies when IBM "validated" that single-user computers were worthy of use by the masses.
Social media was in (almost) the same situation 10 years ago: MySpace was used by a relatively small, but dedicated group, and there were competitors, one of which was Facebook.
It wound up dominating, and has locked up that domination of "the masses" just like Microsoft has.
Does that mean they should not have tried to compete?
It's easy enough to "clone" hardware and relatively software like MS-DOS, Lotus 1-2-3, etc.
Much more so to clone Windows, it's gargantuan API and wide range of end-user (Office), developer (Visual Studio) and Enterprise software (Exchange, SharePoint, SQL Server, etc).
Similarly, cloning those petabytes of user data in Facebook, plus it's API, plus convincing users that there's a reason to change is well nigh hopeless.
if they got it right
The first not-right thing that they did was to not realize that Facebook is a market force like IBM was in 1981, but without the downside of competitors being able to clone the petabytes of data that sheeple have willingly uploaded to Facebook.
Ambition is one thing, but ignoring reality is something completely different.
still pennies compared to the waste in
The problem is that waste is endemic to massive government projects. Most of the voting populace want these wealth redistribution projects more than they want the onerous rules, regulations and oversight needed to eliminate waste.
applying those $10 billion to exploring alternative energy sources, solving diseases, or paying teachers and improving crumbling schools.
Thus, it would really cost $30Bn.
What's there for us on Mars? Some ice, lots of dust and some caves. Nothing else. No atmosphere, no energy, no plants, no *nothing*.
Traveling 45 million miles for that is a completely *stupid* idea.
ISTM that *constantly* blasting out Very High Wattage radio waves in *every* *spherical* *dimension* is just... wasteful. Really, really wasteful. Not to mention really polluting of the EM spectrum.
A constellation of satellites each scanning it's own region of space seems more efficient. They could also use LIDAR in the same way that we make 3D models of rooms and caves.
Those stars are GINORMOUS.
Meanwhile, we need massive radio telescopes to receive messages from the planet next door.
active radar is something that a more advanced race will need more powerful versions of to track things in their solar system
Why not use transponders?
And if they're really advanced, they'll point their radars relatively close to the plane of the ecliptic where all the stuff is.
as to think that:
1) anonymous space aliens are radiating coherent energy in all directions (we sure aren't) and,
2) that we'll pick them up, when receiving photons from stars is so difficult.
But didn't that boat sail 25 years ago?
You *obviously* don't have a family.
