Not at all! Besides, it is the only thing I can talk about with some degree of expertise, imagine if I let such an opportunity slip by...

I would like to see an orchestra playing Mahler's Symphony of a Thousand without a conductor; then one could truly say that it can be done without one.
This, in itself, would be an excellent topic. In fact, one must not forget that the figure of the conductor as we know it has had a very long evolution and consolidated into the "classical" way for purely practical reasons. "Conductors" have been spoken of since the first half of the 1700s, but even JSB conducted (like Gluck and Haydn) from his position as first violin. Conducting from the harpsichord was the norm until Beethoven (who is in fact the first composer to conduct without playing), but for example, for Haydn's "The Creation," in 1785, five conductors were employed (five!!!) because there were so many performers and they were spread out so widely in Westminster Cathedral that it would not have been possible otherwise.
Aside from all this, however, one should also consider a more hidden aspect, which I mentioned above, regarding the musical direction of any piece. You have no idea how many times the classic question has been posed to me, namely: "but the conductor... what does he do? After all, the orchestra already knows what it has to play, right?". And there, you struggle to explain the nuances...
Peter Lichtental wrote, regarding the "1st violin conductor" (a figure that would lead almost naturally to the conductor on the podium, without a violin but with a baton), "does not need to be a concert performer [...] but must possess greater musical knowledge and feeling for art". And, mark my words, Lichtental was born in 1780. Consider that at that time, it wasn't even customary for those who began conducting from the podium and with a baton to use the full score... There were reductions (born specifically for the use of the first violin conductor who needed a guide to give the main attacks), but we have testimony of Angelo Mariani who, to conduct "Stiffelio," asked for the score, "because 'the principal' is used by the so-called shoulder first violin," where by "principal" it most likely meant the so-called "small score" or "leading violin," that is, the part of the first violin with guides for the main voices. This means that knowledge of the score was considered a faculty possible only for the composer (and indeed, a conductor's skills are very similar even today), while whoever conducted had a function that, up to that point, was only practical. This is why Lichtental's observation is significant: even at that time, the need for something deeper than a simple time-beater was beginning to be felt.
Anyway, to finish, I will tell you what explanation I have developed to explain to non-musicians what a conductor does. I use a pictorial metaphor and explain that an orchestra without a conductor would be as if Leonardo had made a pencil sketch of the Mona Lisa, then put down the brushes and colors and told seven or eight painters to paint one the left hand, one the right hand, one the face, one the hair, one the background, one the dress... but simultaneously and without anyone seeing what the other was doing. Of course, everyone had been told which colors should be used for each part of the painting, but... what would have come out?"
