Answer: A tough recruiting market, record high housing prices and 67 hours of time spent in traffic.
This area represents the metaphorical headquarters for tech companies and engineers to find each other and make impossible digital feats possible, but with the already high cost of living continuing to climb it's no surprise some companies have chosen to relocate. The Bay Area prices are making it tough for local businesses to recruit the top talent for their open positions, especially with technology giants vying for that same talent pool living in their backyard. As a result, some companies have chosen to move away from the area in search of a less costly alternative, such as Seattle or Austin, both of which have strong roots in the technology industry. With more affordable housing and expenses in these new locations, these businesses will be able to pay lower wages without sacrificing their employees' quality of life.
Even with these relocations, I don't see this technology hotspot cooling down anytime soon.
