>One must firmly protest these orgies of formalism, with which even technicians are getting harassed today.

(Literally: with which one is beginning to harass even technicians today.) To your questions:

1) *Techniker* is for technicians, engineers, graduates of the [*Technische Hochschule*](https://archive.org/stream/spacetimematter00weyluoft#page/n8) where Weyl gave these lectures, as opposed to scientists or graduates of the University. Applied, not pure.

2) *sogar* definitely applies to *Techniker*, not to *heute*.

3) *belästigen* [=](https://translate.google.com/#de/en/belästigen)
harass,
molest,
bother,
annoy,
irritate,
badger,
pester,
trouble,
importune,
persecute.

**Note added:**<br>
Weyl’s words sound like a veiled attack on F. Klein’s preface to Schouten’s *Affinoranalysis* ([1914](https://zbmath.org/?q=an:45.0190.03)) and its [19+ operations on affinors, deviators, septors, nonors, etc.](https://archive.org/stream/grundlagenderve00schogoog#page/n108):

>Dr. J. A. Schouten was active so far in Rotterdam as an electrical engineer (Elektrotechniker), and got on his own from electrotechnical problems to the theories he outlines in what follows.

>The point is to investigate the geometrical quantities that arise in vector analysis and the Gibbs dyads, triads, etc., on the basis of a group theoretical principle I established long ago: that all geometry is invariant theory under a group, which however one has much latitude in choosing.

>Mr. Schouten’s investigations are all the more welcome, that it is the first time the developments in question, which alone seem to lead to a rational division of geometrical structures, are taken up by a practitioner. Mr. Schouten’s main achievement is that he consistently implements the principle even in higher cases. Of course, some of the resulting higher-order structures already appeared now and then in mechanics and physics, but they had not yet been enumerated in such systematic completeness as is the case here.

Wikipedia [even claims](https://en.wikipedia.org/wiki/Jan_Arnoldus_Schouten#Grundlagen_der_Vektor-_und_Affinoranalysis) that Weyl’s quote targets this book explicitly. However, this seems to rely on overinterpretation by Reich ([1994](https://ams.org/mathscinet-getitem?mr=1353442), p. 157) of an ill-captioned picture in Rowe ([1989a](https://ams.org/mathscinet-getitem?mr=979020), p. 17; [1989b](https://ams.org/mathscinet-getitem?mr=1007032)): Struik ([1971](https://ir.cwi.nl/pub/20360), p. 2) merely writes that “**Schouten** later realized that Weyl’s critique of “orgies of formalism” was **also** applicable to this book” — and Klein also promoted *Theory of Screws* ([1900](https://zbmath.org/?q=an:31.0679.03)) or *Geometrie der Dynamen* ([1903](https://zbmath.org/?q=an:33.0691.01)), among others.
