Agree to disagree. The grand COVID WFH experiment has proven what companies like Basecamp, Zapier, have been advocating for the last few years: a digital first, hybrid environment works and can actually help attract and retain talent. Regardless of COVID employees will be allowed, if they want, to work remotely permanently. Maybe it'll be 60%, maybe 75%, but the days of having your entire team (or 95% of your employees) in one physical location are over. This disruption has been accelerated by COVID, but has been made possible by better collaboration tools (Asana, Slack, Zoom). Tech companies have found that remote can help with: retention, diversification of talent pool, as well as employee satisfaction. I work for a mid-sized tech company and we, and many of our peers, competitors, and partners, are all thinking about the future of our offices in VERY different ways. e.g. we're planning on doubling our staff over the next 12 mo - we haven't spoken about doubling or even increasing our floor plate.
As for the large tech companies (Facebook, Google, Amazon) they are indeed building and buying more office space, but similar to Shopify, are they acquiring more office in concert to their employee growth? Take Shopify as an example: they are indeed moving in to The Well - but given that their headcount has increased by 25% ever year for the last 4 years, are they growing their space by 25-50%?
Right now Shopify has 700,000 square feet committed across 4 Ottawa and Toronto offices (Laurier, Elgin, King and Spadina). When their Well office opens in 2022, they will have 750,000 square feet across both cities which is an increase of 50k square feet (altho they have an OPTION for more space that they haven't full exercised). That's NOT a significant increase of square footage given their growth.
