"I am glad that we are moving away from a time when women in politics could only have a say on so-called women's topics — equal treatment, family policy," Kallas said in a press release. "And sadly, this is often presumed. I have probably stood out as I actively deal with technological and digital topics and energy policy, which have traditionally been considered so-called manly fields.

"When giving talks in Brussels, Estonia and elsewhere in the world, I am often the only woman in panel discussions, and this is why I am especially glad that women have lately begun using their voices more loudly and that their brave steps are also being valued," she added.

Among other tech leaders, Politico also highlighted the female heads of large tech companies in Brussels, three European Commissioners coordinating technological topics, six female MEPs, and two journalists who report on the topic of technology.
