Retail spaces will suffer because products availability on mobile devices has make shopping easier, better comparison and faster to order (more so with eCommerce trying to achieve same day delivery). Even services-oriented proprietors (F&B, lifestyle services like spa, salon etc) are moving online; there is little chance retail will come back.
Human behaviour has evolved; now people go to retail stores to see those products they want, touch and feel it, then they will browse the web in search for cheaper prices and purchase those products online.
If you want to prevent your money going down the drain, avoid retail business. And if you are already in retail, time to transform from brick & mortar to click & order.
