The world害羞草研究所檚 largest tech conference has apparently learned a big lesson about gender equity.

CES, the huge annual consumer-electronics show in Las Vegas, caught major flak from activists in late 2017 when it unveiled an all-male lineup of keynote speakers for the second year in a row. Although it later added two female keynoters , the gathering害羞草研究所檚 害羞草研究所渂oys害羞草研究所� club害羞草研究所� reputation remained intact. It didn害羞草研究所檛 help that one of the unsanctioned events latching on to CES last year was a nightclub featuring female 害羞草研究所渞obot strippers.害羞草研究所�

This year, four of the nine current keynoters are women. GenderAvenger, the activist group that raised a ruckus last year, recently sent CES organizers a congratulatory letter and awarded the show a 害羞草研究所淕old Stamp of Approval害羞草研究所� for a roster of keynote and 害羞草研究所渇eatured害羞草研究所� speakers that it says is 45 per cent women 害羞草研究所� 60 per cent of them women of colour.

It害羞草研究所檚 a significant change for CES, which like most tech conferences remains disproportionately male, just like the industry it serves. Even absent the robot dogs, sci-fi worthy gadgets and 害羞草研究所渂ooth babes害羞草研究所� CES has been known for, you could readily peg it as a technology show from the bathroom lines alone 害羞草研究所� where men shift uncomfortably as they wait their turn while women waltz right in.

Keynoters this year include IBM CEO Ginni Rometty; Lisa Su, CEO of chipmaker Advanced Micro Devices; and U.S. Transportation Security Elaine Chao. The entire featured speaker list is currently half female, although the exact percentage won害羞草研究所檛 be known until after the event. 害羞草研究所淭here is no question we keep trying to do better,害羞草研究所� said Gary Shapiro, CEO of the Consumer Technology Association, which organizes CES.

害羞草研究所淒iversity is about having people who see things differently 害羞草研究所� frankly, disagree with you and tell you that you are stupid,害羞草研究所� said Tania Yuki, CEO of social media analytics company Shareablee and an attendee of CES for the past several years. The big question, she says, is whether CES has really listened to its critics.

CES is the place to be for tech companies and startups to show off their latest gadgets and features. More than 180,000 people are expected to attend this year, and some 4,500 companies will be on the convention floor. Among them are newcomers like Tide maker Procter & Gamble, defence contractor Raytheon and tractor seller John Deere 害羞草研究所� all eager to burnish their technology bona fides.

But really levelling the playing field often means more than inviting female CEOs to speak. For starters, women and people of colour are underrepresented in the tech industry, especially in leadership and technical roles. So, conference organizers might need to look harder, or be more flexible in who they invite to speak.

There are also optics. While recent attendees say 害羞草研究所渂ooth babes害羞草研究所� 害羞草研究所� scantily clad women hawking gadgets 害羞草研究所� no longer seem to be a presence, some companies still hire 害羞草研究所渇itness models,害羞草研究所� largely young women wearing tight-fitting outfits, to demo products. This can make it difficult for the few women at the show who are there as executives, engineers and other technologists, as men mistake them for models, too.

害羞草研究所淲hen you are talking about scantily clad models you are setting a tone,害羞草研究所� said Bobbie Carlton, the founder of Innovation Women, a speaker bureau for women. 害羞草研究所淚t is a slippery slope and you end up with this type of mentality that runs through industry, where women are objectified and are only useful if they look good.害羞草研究所�

More optics: Until recently, a porn convention taking place immediately after CES appeared more diverse than CES itself. Not a good look for the tech confab.

There are also logistical challenges, Carlton said. For example, women often work for smaller companies, which can find it more challenging to 害羞草研究所渟end someone cross-country to stay at a fancy hotel for three days,害羞草研究所� she said.

Rajia Abdelaziz is CEO of invisaWear, a startup that makes smart 害羞草研究所渟afety jewelry.害羞草研究所� While she害羞草研究所檚 attending CES this year, she said it wasn害羞草研究所檛 worth the $10,000 it would cost her company to have its own convention-floor booth. In addition to the cost concerns, Abdelaziz notes that her products are primarily aimed at women 害羞草研究所� and there just aren害羞草研究所檛 that many of them at CES.

Women are also still more likely to be responsible for the home and for child care, so they might turn down speaking opportunities if the timing doesn害羞草研究所檛 work for them, Carlton said.

CES has tried to make some concessions. For example, it offers private pods for women to pump breast milk at the event. But it doesn害羞草研究所檛 offer child care support, unlike the smaller Grace Hopper Celebration for Women in Computing conference, a fall event aimed at women in computer science.

Organizers note that children are not permitted at CES. Although kids are also banned from Grace Hopper, that conference still manages to offer free child care for attendees.

Still, Yuki is hopeful that CES is on the right track. 害羞草研究所淚t害羞草研究所檚 a big conference,害羞草研究所� she said. 害羞草研究所淵ou can only turn a very big ship very slowly.害羞草研究所�
