Fabrice Bellard

I used to find myself making USELESS softwares.
But Fabrice Bellard is a larger version of me. He has better mathmatics skills than me. and better in language multipling.
But same as me, he really makes USELESS things.
see:

2700 billion decimal digits of Pi,
A PC emulator in Javascript,
TCCBOOT,
TinyGL,

what's the fucking use of these.
And another same point with me is to make things SMALL.

I really made one software useful now is neoeedit, though it seems few people use it except me.


And I'm curious about what his job is, what making a living. I often works as a software worker what I didnt like it much.
He gets money from gov's welfare to keep poor?
