No, it is not.  Is very relevant.

But nothing I will say could ever penetrate your prejudice --
a prejudice which is based on much misinformation.

Computational physics is quite a fundamental area both of
application and of theoretical research, and the thorough
understanding of FP is crucial.

You evidently have never performed numerical analysis
of any kind beyond the use of a "canned" package.
Therefore, I can only conclude that you are unqualified
to form a definitive opinion on the matter.

Maybe, but it sure is fun.

You should try it sometime.  Yeah, put away your stuffed shirt
and try it.

Are they?  Funny, I don't seem to have noticed.

Let me enlighten you, sir, to the fact that many important Linux software
is available ONLY as a tarball and MUST be compiled.

Let me enlighten you, sir, to the fact that the very popular Gentoo Linux
distribution is based entirely on tarball compilation.

Also, there never were any golden days of extracting tarballs in Linux.
From the very beginning there have always been package managers AND
tarball compilation.  In fact, not much has really changed at all.

Please be accurate in your reporting.

No one has worries because few CAN worry, that is, few have the competence
to even know that worrying may be necessary.

The 387 FP unit is NOT obsolete.

You call the "new" FP unit the "multimedia" FP unit.  This only
demonstrates your lack of technical understanding.

The "new" FP unit embodies the SIMD instruction set, which means
Single Instruction Multiple Data.  The fact that SIMD can be
used for multimedia purposes does not make the unit a "multimedia unit."

But most likely all that you do with your computer is watch YouTube
videos, and because of that you claim an authority.

GPU FP is not standardized.  Use it at your own risk.

For your YouTube Mickey Mouse videos is does not make a difference.

But for serious scientific computation it sure as hell does.

It is that way because there are professional who DO take an
active interest.  Their work, behind the scenes, insures that,
among other things, your YouTube Mickey Mouse is jitter free.

Until you start pissing blood, then you run to the specialist
and beg for the knowledge and expertise that you could never attain.
