I have been invited to but turned down 3 conferences talks already this year because they're told me it's new policy to not cover speaker travel under the assumption that your tech employer will cover it. I own my own small business as a researcher and my wife is an academic teaching professor, so I cannot ask my household to absorb that. I just want to generally observe that we are filtering the voices we're going to be able to hear from, with all this contraction
Edit for clarity: this is a criticism of conference organizers, and most certainly not directed at Cat or her choices.
And yet over the past year I've "attended" three conferences without leaving my desk, featuring several presenters who also did not leave their desks.
I would be turning such invitations down on the basis of carbon emissions alone. Yes I know the in-person experience is superior, but I'm not willing to sacrifice future generations for that.
